Ever since a back injury prematurely ended his freshman season, Kansas center Joel Embiid has been out of sight, out of mind when it comes to NBA draft discussions. Embiid, who declared for the draft on Wednesday, is far from a finished product, but he would dramatically improve every team in the lottery. There’s no one else on the draft who can replicate his impact on both sides of the ball. Embiid is the No. 1 prospect in 2014 and it isn’t really close.

Embiid had good statistics for a freshman - 11 points, 8 rebounds, 2.5 blocks, 1.5 assists and one steal a game - but they don’t fully capture how dominant he was. His biggest problem was foul trouble, which is what you would expect for a guy who started playing basketball three years ago. His per-40 minute numbers were outrageous - 19 points, 14 rebounds, 2.5 assists, 1.5 steals, 4.5 blocks and six fouls on 63 percent shooting. He’s a 19-year-old center with a 28.2 PER.

When Embiid was in the line-up, Kansas looked like one of the best teams in the country. Without him, they looked like a team that was replacing four senior starters and a lottery pick (Ben McLemore). Their tailspin at the end of the season coincided with Embiid’s absence. They went 3-3 in their last six games, including a loss to an NIT team (West Virginia), struggling with a 15-seed in the first round of the NCAA Tourney and losing to a 10-seed in the second.

Andrew Wiggins, his more celebrated teammate, had 41 points in the game against the Mountaineers, but he wasn’t making his teammates better. Without Embiid, Kansas couldn’t control the tempo of the game or protect the rim, allowing West Virginia to get the game going up-and-down and race out to a 50-38 halftime lead. Wiggins took 18 shots in that game, but he had only two assists on four turnovers. That’s not the ratio you want from your best player.

It’s much harder for a big man to rack up assists than a perimeter player, yet Embiid and Wiggins both averaged the same number on the season. When Wiggins gets the ball on the wing, he’s putting his head down and making a straight-line drive at the rim. When Embiid gets the ball in the post, he’s collapsing the defense and moving it back out. Even though he’s far less experienced, Embiid showed more court awareness than Wiggins this season.

For all the talk of Wiggins’ athletic ability on the defensive end, Embiid averaged only 0.3 fewer steals a game, despite spending most of his time in the paint. A great interior defender, as the second line of defense, is far more valuable than a great defender on the perimeter. Just by standing in the middle of the lane, Embiid covered up a lot of mistakes on the defensive end and made everyone better. There’s no way for a guard to replicate that kind of impact.

When people talk about the draft, everyone brings up Sam Bowie over Michael Jordan and Greg Oden over Kevin Durant. At the same time, you don’t hear many people talking about taking Evan Turner over Derrick Favors or all the teams that passed on Andre Drummond. The media would like you to believe that basketball games are won and lost by which team’s perimeter players can hoist more shots and “impose their will” on a game, but that isn’t the case.

If you make a list of the best centers in the NBA, you will start to notice a trend - they all play on really good teams. Dwight Howard, Marc Gasol, Joakim Noah, Tim Duncan, Roy Hibbert and Andrew Bogut are all centerpieces of good teams. The only good center on a bad team (DeMarcus Cousins) is the exception that proves the rule - he’s the rare center who doesn’t play much defense. If you paired him with Embiid, it would be a serious problem.

It’s no coincidence that Gasol, Noah, Duncan, Hibbert and Bogut all made the second round of the playoffs last season. The other three centers? Tyson Chandler, Chris Bosh and Kendrick Perkins. Unless you have LeBron James or Kevin Durant, you had better have a good center. In case you were wondering, there aren’t any 6’11 235 SG’s with a 7’4 wingspan or 6’9 270 point centers in this draft. Embiid is the one guy who brings instant credibility to the team that drafts him.

Embiid makes his teammates better on both sides of the ball. He’s the rare 7’0 who has a chance to be an elite defensive player and an elite offensive player. He has the physical ability to be a Defensive Player of the Year candidate and the skill-set to be indefensible in the low post. In terms of his ceiling, Embiid is more fluid offensively than Howard, more athletic than Gasol, more skilled than Hibbert and Bogut and much bigger than Noah. His ceiling is Tim Duncan.

There are a lot of parallels between Duncan and Embiid. Both picked up the game later in life - Duncan was an elite swimmer in the Virgin Islands, Embiid grew up playing volleyball and soccer. As a result, neither picked up the bad habits that plague modern big men. They aren’t trying to play point guard or shoot a bunch of 3’s - when you are bigger, faster and more coordinated than everyone you face, you don’t want make the game any more complicated than it has to be.

That’s the most intriguing thing about Embiid - he’s a 19-year-old still growing into his body, yet he’s already bigger and faster than most NBA centers. He won’t come in and dominate his competition as a 20-year-old, but he will be able to hold his own. Even if I had a center on my team, I would draft Embiid and make him a PF, just like Duncan. He’s fast enough to play on the perimeter and he shoots 69 percent from the free-throw line - he’s capable of playing out of the high post.

Andrew Wiggins is a great prospect, but there are super-athletic wings who can’t pass the ball in every draft. If Embiid never gets better, he is a more offensive-minded Tyson Chandler. An NBA team doesn’t get a chance to draft a 7’0 with his ability very often - there aren’t many drafts where Embiid wouldn’t be the No. 1 prospect. He’s the only player in this draft I would seriously consider tanking for. If the doctors clear him medically, you take Embiid without thinking twice.
