Last fall on Basketball Prospectus I introduced the first ever lineup-based statistical model. Today, I use that model to project the 2013-2014 ACC college basketball standings:

Proj CW, CL = Projected conference wins and losses

Proj Off, Def = Projected points scored and allowed per 100 possessions against an average D1 team on a neutral floor

Top 100 = Number of players ranked in the RSCI Top 100 out of high school who are on the roster 

Ret Min, Ret Poss = Returning minutes and possessions

Last Off, Last Def = Last year’s offense and defense

Duke: Quinn Cook, Andre Dawkins, Rasheed Sulaimon, Mississippi St. transfer Rodney Hood, Amile Jefferson, #2 recruit Jabari Parker. Yes, Duke is going to be dominant again.

North Carolina: Marcus Paige, PJ Hairston, Leslie McDonald, James McAdoo, and four high potential young forwards (either ready to make the sophomore leap or contribute from day one) should make for a dominant lineup.

Virginia: At the start of April I wrote this: “Everything is coming together for Virginia. They have their three top scorers (really the only guys who scored at all) back from last year. Former Top 100 recruit Mike Tobey should be ready for that sophomore year leap in production. They add depth with South Carolina transfer Anthony Gill. Malcolm Brogdon (who missed the entire season) and Darion Atkins should be back healthy. And Virginia played very good basketball in conference games last year.” The only question mark is point-guard. London Perrantes, Teven Jones, and/or Devon Hall have to come through for this team to meet its expectations. And while at #97 ESPN recruit Perrantes isn’t a sure thing, the model thinks he will easily exceed the efficiency of Jontel Evans. Evans couldn’t shoot at all last year and posted an 83.4 ORtg. When a team loses its most inefficient players and has solid replacements coming in, that team should be substantially improved.

Syracuse: Unfortunately, Syracuse seems poised for another brutal offensive year. There were basically only four guys on the team that could score last year, and three of them are gone. The real problem is the lack of depth on the perimeter. My model has Duke transfer Michael Gbinije playing some minutes at the shooting-guard spot, but as Georgetown saw last year when they tried to play Otto Porter at that spot, a four forward lineup doesn’t have the right spacing. This is especially true given that among Syracuse’s returning forwards only CJ Fair has a true jump shot.

That means Syracuse will have to give a lot of minute to Tyler Ennis, Trevor Cooney, and Ron Patterson. Tyler Ennis might have a higher recruiting rank than Virginia’s London Perrantes, but he still isn’t a guaranteed star where he is rated. And Trevor Cooney was brutal last season. While the model predicts Cooney will be better this year, he certainly can’t be counted on to be a star. And Syracuse hasn’t had much success utilizing unranked freshmen right of the bat which isn’t good for Ron Patterson’s expectations.

DaJuan Coleman might become a high scorer next year, but it is a catch-22. While he is the only returning player who was a high volume shooter, he wasn’t very efficient (89.1 ORtg) last year. Part of that was an injury issue, but even with a fairly sizable jump in efficiency this year, he won’t be able to carry the offense. Don’t be fooled by transfer Michael Gbinije’s ORtg on Statsheet.com. He basically never played for Duke two years ago. The fact that he didn’t play says more about his expectations then whatever numbers he posted in garbage time in a few games. And don’t be fooled by Baye Moussa Keita’s efficiency either. Keita basically never shot last year. Syracuse has eight former Top 100 recruits on the roster, so they have talent. But it isn’t quite the right fit to expect a dominant offense.

Where I think the model may be wrong is not the offense, but the defense. The model is skeptical because Jim Boeheim has only had an adjusted defense below 89.0 once in his career. That one year was last season, so perhaps it will be repeatable. But Michael Carter-Williams had rare size at the PG spot. He made it brutally hard for teams like Indiana to get open looks at three and for players to make basic entry passes. If Cooney and Ennis can duplicate that, then Syracuse may be a Top 10 team.  My model expects a solid but not historic defensive performance from Syracuse.

Pittsburgh: This is going to sound odd, but Pittsburgh probably has a better starting rotation than Syracuse. Talib Zanna was Pittsburgh’s best forward last season. James Robinson was impressive as a first-year PG, and Lamar Patterson was a do-everything player. Meanwhile, JJ Moore is back and he was Pittsburgh’s most efficient bench player. The team also adds highly ranked freshman recruit Mike Young at forward. The real weakness for Pittsburgh is going to be depth. After those five guys, there is a serious drop-off. But keep in mind that Jamie Dixon has only finished with more than six conference losses once in his career. That isn’t going to change even in a stacked ACC.

Maryland: Replacing Alex Len won’t be easy, but the combination of Shaquille Cleare and Charles Mitchell’s development, combined with the addition of a lights out perimeter shooting forward (Michigan transfer Evan Smotrycz) should make it palatable. Pe’shon Howard was so inefficient at the PG slot that his departure is probably addition by subtraction.

Notre Dame: For those of you keeping track, despite being listed as seniors last year, Garrick Sherman and Tom Knight are coming back. I am most interested to see how Mike Brey utilizes freshmen Demetrius Jackson. Brey usually has a short-leash with freshmen. The exception was Luke Harangody, and Jackson might just be that kind of freshmen. What is holding Notre Dame back is that Mike Brey is not an elite defensive coach. And that means the loss of a premiere defensive rebounder like Jack Cooley is a real problem.

Florida St.: Somehow, despite a horrible non-conference season, and terrible margin-of-victory numbers, the Seminoles won nine ACC games last year. I expect Florida St.’s offense and defense to be substantially better than last year. But I don’t expect them to match last year’s exceptional luck. And in an improved ACC, I project Florida St. as a 9-9 team. They will be better, but they might not have more conference wins to show for it.

Of course, if Andrew Wiggins matriculates, this expectation will be much higher.

Looking back, it is hard to believe how dreadful Florida St. played at times last season. The Seminoles scored 36 against Virginia and an even more embarrassing 46 against defensively challenged Wake Forest.  Highly rated freshman Montay Brandon had one of those avert-your-eyes awful seasons. It was amazing how much Leonard Hamilton stuck with him despite his clear offensive struggles. Brandon’s poor performance shows the difference between an old-school coach and a new-school coach. Buzz Williams and Brad Stevens would have never let a player like Brandon waste so many possessions.

But despite these offensive concerns, the real problem was the defense. How did one of the top defensive coaches suddenly forget what he was doing? I think the injury to Ian Miller had a lot to do with it, but the overall team performance was head-scratching. With a healthy Ian Miller, I predict a substantial bounce-back on both ends of the court. But it also depends on Hamilton making better lineup decisions than last season.

Boston College: Notre Dame transfer Alex Dragicevich will add to the team’s depth. But until Boston College starts playing better defense, they won’t make the tournament.

NC State: If you ask Mark Gottfried, he will admit that the lack of depth last year was frustrating. It made it hard to hold legitimate practices. But thanks to a host of defections NC State only has eight scholarship players again. One of those eight players, Jordan Vandenburg has struggled to ever earn playing time and was injured for much of last year. It is possible Vandenburg will break out as a fifth-year senior, but the expectations cannot be that high. The other seven players (including LSU transfer Ralston Turner and JUCO addition Desmond Lee) should all be solid players. But at this point, you have to bank on extreme luck to even put together a decent rotation. No one can get injured. None of the prized recruits can be a bust.

And Mark Gottfried hasn’t exactly been the kind of guy to bring a new crop of recruits together and play top defense right away. NC State probably has a higher upside than some of the teams listed ahead of them, but the downside risk is pretty high too. If everyone (but Vandenburg) comes back, this team will be in much better shape in 2014-15.

Wake Forest: Wait, why is Jeff Bzdelik still the head coach? Senior Travis McKie deserves better.

Georgia Tech: Marcus George-Hunt and Robert Carter were solid scorers as freshman last season and as highly ranked high school recruits, there is no reason to think they won’t make the sophomore leap and become stars this year. Overall Georgia Tech’s offense would be rated higher, but there is a major question mark at the PG slot. Solomon Poole wasn’t ready last year, but the alternatives Corey Heyward and Travis Jorgenson don’t have obvious pedigrees either. Without a strong point-guard and with several offensive liabilities in the rotation, the offense will still be bad.

Clemson: Given that they lose their two best players and have zero players who were elite high school recruits on their roster, I think a lot of preseason predictions will have them even lower than this. There really isn’t anyone on the roster who looks like a likely offensive star. (The only good news is that Clemson was young last year and the sophomore leap should help at least a couple of their freshmen become solid players.) But let’s face it, this is going to be an ugly team to watch. The only reason the model doesn’t have Clemson lower is because of Brad Brownell’s ability to teach defense.

Miami: Give Jim Larranaga credit for what Miami did last year, but this is a rebuilding year. This team was just devastated by graduations and Shane Larkin’s early entry into the draft. I think the lineup-based model may be a little too pessimistic. But the best-case scenario here is probably what Vanderbilt did in the SEC last year.  Don’t count on much from guys like Tony Jekiri and Erik Swoope. Guys who shoot that little rarely become big scorers. I feel bad for Rion Brown.

Virginia Tech: Goodbye Erick Green. Yep, next year isn’t going to be any better.

Last fall on Basketball Prospectus I introduced the first ever lineup-based predictions model. Even -though I intend to make improvements to the model over the summer, since I already have the programming code written, today I wanted to rerun the first version of the model and see what it tells us about the 2013-2014 season.

The biggest problem is guessing which players will declare for the draft. I haven’t seen an official announcement for Nerlens Noel or Shabazz Muhammad, but I think it is clear they are both leaving. I also assume that anyone who can make this year’s lottery would be foolish not to leave. Thus I assume Ben McLemore, Marcus Smart, Victor Oladipo, Otto Porter, and Trey Burke are gone. Michael Carter-Williams never struck me as an obvious lottery choice this year, but the consensus seems to be that the scouts like his size and NCAA tournament play, so I project him as leaving.  Similarly a slew of big guys seem likely to go pro from Gorgui Dieng, to Cody Zeller, to Alex Len, to Kelly Olynyk.

Notably, I’m not going to assume Doug McDermott and Russ Smith come back. I understand there isn’t much more they can accomplish in college, but based on the draft projections I have seen, neither player is guaranteed to be a first round pick right now.  I think that if you are not certain to get a guaranteed contract in the NBA, the risk of leaving is pretty high. Thus I’m going to assume these players return, even though that may be a dubious conclusion.

 Key:

Pred Off, Pred Def, Pred Pythag: The predicted points scored and allowed per 100 possessions, and predicted winning percentage against an average D1 team on a neutral floor.

Returning Minutes, Possessions: The loss of high possession players can be a larger detriment to the offense, thus I list percentage of returning possessions in addition to returning minutes.

T100: Number of players who were Top 100 recruits out of high school. People focus on Top 100 freshmen, but Top 100 players are also more likely to become breakout stars later in their career.

Last Pythag: Last year’s Pythagorean winning percentage according to Kenpom.com. This is essentially a measure of each team’s margin-of-victory in 2012-13.

Kentucky: The Wildcats have the most talent by far, and the most NBA potential, by far. The only question is time. Can John Calipari teach such a wide array of talent to play together in one year? In three of his four years, John Calipari has managed to get the Wildcats to play elite defense. The model hedges its bets and says the defense might not come together that quickly. (The fact that defense-lacking Kyle Witjer is still going to play meaningful minutes is also a concern.) But with all those Top 20 recruits, and all those highly ranked returning sophomores, it is very hard to predict anything other than a special offensive team.

Michigan St.: I’m assuming Gary Harris is coming back based on Tom Izzo’s comments. When a Top 10 Big Ten squad returns basically all its key players, it is hard not to have high expectations. Kenny Kaminski will be healthy. Denzel Valentine and Matt Costello both remain high potential guys who should see a sophomore leap in efficiency. And Harris, Keith Appling, Branden Dawson, and Adreian Payne are as good a returning set of four starters as you will find. Michigan St. might not be the most talented team in the country, but they have fewer lineup questions than just about anyone.

North Carolina: The Tar Heels will be back. The two biggest lineup issues this year were point-guard and one of the forward slots.  We already saw glimpses of point guard Marcus Paige’s improved play late in the year and he should be a star in year two. I can’t tell you exactly who will develop as a post compliment to James McAdoo, but someone will. Whether it will be freshman Isaiah Hicks or Kennedy Meeks, or (after a summer of working out in the gym) Brice Johnson or Joel James, the Tar Heels have four former elite high school post players to choose from. At least one of them will be ready. Overall, North Carolina has more Top 100 talent than anyone else.

Louisville: With players like Montrezl Harrell playing well in limited time this year, Louisville has a chance to go to the Final Four again. But this high ranking depends on Russ Smith’s return. Without Smith, the team will be putting a heavy burden on incoming freshman point guard Terry Rozier. Rozier isn’t in this year’s ESPN’s Top 100 because he needed a year of prep school, but he was a consensus Top 100 recruit last year. RSCI had him 75th.

Florida: Don’t be scared away because the Gators return only 54% of their offense from last year. The Gators add two instant impact recruitsin Kasey Hill and Chris Walker, along with two transfers who were former Top 100 players, Damontre Harris and Dorian Finney-Smith. If the point-guard Hill lives up to his hype, Florida might be even better than last year. They will certainly be deeper.

Michigan: The further development of Mitch McGary, Glen Robinson, and the addition of another stellar recruiting class should help overcome the loss of Trey Burke. But if additional players declare for the draft, Michigan’s expectations could slip.

Arizona: My gut tells me Arizona may be a little too low here. Arizona loses a lot of production, but they have the right pieces coming in. Point guard TJ McConnell was phenomenal at Duquesne and unlike Mark Lyons, McConnell is more of a natural PG. Aaron Gordon and Rondae Hollis-Jefferson should be instant-impact recruits. And the returning sophomores on the front line should be better in year two. The model is mostly concerned whether Sean Miller can bring together an elite defensive team. Last year was Miller’s best defensive team yet, but it still wasn’t an elite defensive team. Until Miller gets his team to play great defense for a full season, there will always be reasons to be skeptical.

Marquette: Vander Blue, Davante Gardner, and Jamil Wilson are back. Buzz Williams has his best recruiting class yet, and the team should have more Top 100 talent than it has ever had in his tenure. Plus Buzz Williams gets the most out of his players by studying the data and eliminating bad possessions. Still, even if the model likes Marquette as a top 10 team, I am concerned that Williams typically has a short-leash with his freshmen. And if they don’t contribute, Marquette may still lack the talent to be an elite team.

Duke: Quinn Cook hasn’t been dominant yet, but he was a Top 10 recruit out of high school, and he is still a high potential player. Andre Dawkins should return from his sabbatical and paired with Rasheed Sulaimon on the perimeter, the Duke back-court looks strong. In the front-court, Amile Jefferson was a solid offensive player when filling in for Ryan Kelly and Jabari Parker is an instant impact recruit. And don’t overlook Mississippi St. transfer Rodney Hood. Duke loses a lot, but the lineup still looks dominant.

Wisconsin: Once again, a model based on the tempo free numbers loves Bo Ryan’s squad. I’m skeptical, but the lineup does look legitimate next year. Remember Josh Gasser is coming back after missing all of last year with an injury. The team’s most important scorer Ben Brust is back. Frank Kaminsky played well in limited minutes. And most importantly, Sam Dekker might be the best post player Bo Ryan has ever had. Seriously, the Badgers lose 45% of their possessions from last year, and the tempo free model still loves them.

Parity is the big storyline headed into the NCAA Tournament, as there doesn’t appear to be a team capable of lapping the field like North Carolina in 2009 or Kentucky in 2012. But while it's hard to argue now that last season’s Wildcats (38-2 with six players drafted) weren’t a great team, there was plenty of parity talk as it happened. On some level, the whole conversation is just an exercise in thinly-disguised nostalgia, another in an endless series of complaints from Baby Boomers about how great things were in their day. It’s hard to get a read on who will be cutting down the nets in Atlanta, but that’s not as big a deal as many would have you believe.

None of the top teams have separated themselves from the pack this season, in part because there are some striking similarities within the Top 10. Just like in the NBA, floor spacing has become the name of the game at the top of the NCAA. Nine of the top 12 seeds start a three-point shooter in their frontcourt, whether it’s a small forward shifted down a position or a “stretch 4”, a category of player that didn’t exist a generation ago. There’s an underlying principle behind what many of the best coaches in college basketball are doing: get as much shooting on the floor as possible without compromising your defense and rebounding.

Indiana has Christian Watford, Gonzaga has Kelly Olynyk, Miami has Kenny Kadji, New Mexico has Alex Kirk and Florida has Erik Murphy. Duke lost in the first round last season without Ryan Kelly (“The White Raven”) and they were a completely different team this year when he was injured. A year after Ohio State started Jared Sullinger at the 4, they’ve replaced him with DeShaun Thomas, a 6’7 225 small forward. Michigan State has Adreian Payne, the most intriguing of the bunch because he’s also an athletic 6’10 240 center capable of protecting the rim and controlling the paint.

The Blue Devils' struggles without Kelly are a good example of the importance of the position. Kelly, at 6’11 230, is a dead-eye shooter who takes four 3’s a game and knocks them down at a preposterous 49% clip. He makes nearly every open shot he gets and his high release point means he needs very little space, if any, to be open. As a result, Kelly's defender has to hug him along the three-point line, creating space for the other Duke players. Mason Plumlee, an athletic 6’11 235 center with a fairly mechanical post game, looked like a Wooden Award candidate when Kelly was playing. Without the space that Kelly provided him, he went back to being a role player.

Space is the most important thing that a modern player needs. Since the top players are bigger and more athletic than they were a generation ago, there is less room on the floor to operate than there used to be. At the same time, most players don’t come into college with the ability or patience to run a halfcourt offense. The AAU game is mostly up-and-down transition action, with rosters put together and taken apart in the span of a weekend. As the Miami Heat are showing this season, continuity takes years to develop, years that most college coaches no longer have.

Increasing the amount of space on the floor is a way to short-circuit that. A pick-and-roll with three shooters spotting up doesn't require a complicated decision-making process. The guard makes a basic read -- take the shot or hit the roll man -- and then looks for the only possible defensive counter -- sending a help-side defender from the three-point line. Florida, a program which hasn’t exactly been known for halfcourt execution, has used that design to great effect this season. Scottie Wilbekin and Patric Young play a two-man game and Murphy, Mike Rosario and Kenny Boynton spot up off of it. The only real defense for it is to have superior athletes, one reason why the Gators, a team with really good athletes, have a 26-7 record.

Without great spacing, defenses can pack the paint and dare the offense to shoot over the top of it. That’s the problem UNC had for most of the season, since neither James McAdoo nor any of their three freshmen centers can stretch the floor. After an embarrassing 87-61 loss to Miami that dropped them to 16-7, Roy Williams turned around their season by going small, moving McAdoo to the 5 and starting four perimeter players. They are 9-3 since the move, with their only losses coming to Duke and Miami. It wouldn’t have worked without two McDonald’s All-American wings (Reggie Bullock and P.J. Hairston) who have the athleticism to defend bigger players, but having the more talented players is why you coach at UNC in the first place.

There are other ways to work around the floor spacing problem, but they generally come with problems of their own. Louisville doesn’t have a frontcourt shooter because Rick Pitino likes to play an aggressive trapping defense that forces turnovers and gets the Cardinals out into the open court. The issue for Pitino’s teams is they eventually run into a disciplined team they can’t speed up and who keep them in the halfcourt, where the questionable decision-making of guys like Russ Smith becomes an issue. Georgetown runs the Princeton offense and Kansas plays a lot of high-low with two big men, but they’ve both lost to far inferior teams this season when their halfcourt offense stagnated.

My guess is that whoever ends up winning the Tournament will be able to space the floor from their frontcourt. That, of course, doesn’t really narrow it down all that much. Almost all of the best college teams maintain NBA-level spacing, a good indication of where the sport is going. A generation ago, almost no big man had a perimeter shot. These days, not being able to space the floor is a significant negative for a player, regardless of the position he plays. Four of the six players in this season’s Three-Point Shootout -- Paul George, Steve Novak, Ryan Anderson and Matt Bonner -- were 6’9+. The era of the stretch 4 is upon us; March Madness is just the latest example.
