Lute Olson, head coach of Arizona, says he expects sophomore Marcus Williams to enter the NBA draft but freshman Chase Budinger to stay for another season with the Wildcats.

"Marcus has made it pretty clear from when he didn't put his name in last year that he would put his name in this year," Olson said Tuesday at his weekly news conference. "That is pretty much a given."

Lute Olson, legendary head coach of the University of Arizona, labeled speculation that he has Parkinson?s disease ?a vicious, vicious rumor? that is ?totally false.?

The 72-year-old coach brought up the subject at his weekly news conference on Tuesday.

?I have gotten some calls about rumors and certain radio stations running some things about me having Parkinson?s, which is a complete lie,? Olson said. ?I have physicals like everyone else does. There is absolutely no medical indication of any type of problem.?

Tennessee men's coach Bruce Pearl painted himself orange and cheered in the student section for the women's game against No. 1 Duke on Jan. 22. Pictures and video of Pearl were very popular online and on highlight reels for several days afterward.

Lady Vols coach Pat Summitt said then she was planning a similar gesture for a men's game, and now her time has come.

Summitt and her staff are planning a special appearance during Tennessee's game Tuesday night against No. 5 Florida.

Ohio State took over the No. 1 spot in the AP college basketball poll Monday, the first time the Buckeyes have held the top ranking since 1962 when they were led by Jerry Lucas and John Havlicek.

Led by freshmen Greg Oden and Mike Conley Jr., Ohio State advanced one day after beating Wisconsin in a meeting of Nos. 1 and 2.

"You hate there had to be a team that lost that game," Buckeyes coach Thad Matta said Monday, referring to his team's 49-48 victory that clinched a second straight Big Ten title. "Fortunately for us we made the bucket at the end and came away on top."

Ohio State moved up one spot in the rankings, receiving 62 first-place votes and 1,786 points from the 72-member national media panel. It is the Buckeyes' first time as No. 1 in the AP rankings since the final poll of the 1961-62 season.

Greg Oden played in his 13th home game as an Ohio State Buckeye on Sunday.  The 49-48 win over Wisconsin, good for the Big Ten title might be a nice way for him to close his days playing in Columbus.

"We're not done yet," Oden said. "I really can't answer that question, because I don't know my decision."

Terry Martin scored 18 points and Garrett Temple added 17 to help struggling LSU upset No. 3 Florida 66-56 on Saturday.

Tasmin Mitchell scored 11 for LSU, which had lost three straight and nine of 10 before hosting a team that had been No. 1 little more than a week ago.

For LSU, the game offered an opportunity to salvage a good memory from an otherwise lost season. The home crowd roared its approval during the waning minutes, while the student section chanted "Over-rated," in Florida's direction.

Florida, which had already wrapped up the SEC regular season title and had set a new school record for single season victories, had little riding on the game and played like it.

Wisconsin's first taste of a No. 1 ranking turned sour Tuesday.

Even so, the Badgers made no excuses after falling 64-55 at Michigan State in their first game in school history as the top-ranked team in the AP poll.

"I don't think that had anything to do with it," Wisconsin coach Bo Ryan said of the pressure of playing with the top ranking in the nation. "Michigan State played better."

Especially Drew Neitzel. The junior guard scored 28 points and hit several key shots in the second half to give Michigan State its first win over a top-ranked team since the Spartans defeated Indiana State in the 1979 national championship game.

Get ready for another 1 vs. 2 showdown in the Big Ten -- this time on the hardwood.

Wisconsin was the new No. 1 in The AP Top 25 poll on Monday and Big Ten rival Ohio State was not far behind at No. 2.

The Badgers, on top of the poll for the first time in school history, play the Buckeyes in Columbus on Sunday -- just a bit more than three months after Ohio State and Michigan played a much-hyped 1 vs. 2 football game at Ohio Stadium.

Florida's 83-70 loss at Vanderbilt on Saturday snapped the Gators' 17-game winning streak and dropped them from the top spot in the media poll for the second time this season.

The new rule that says players must be at least one year removed from high school before entering the NBA is "the worst thing that's happened to college basketball since I've been coaching," says Texas Tech coach Bob Knight.

In the Big 12, it might be called the Kevin Durant Rule after the Longhorn freshman who has electrified the entire country and leads the conference in both scoring and rebounding. Instituted last year by the NBA, it means that super-talented players must wait at least a year rather than jumping into the pros right out of high school.

"Because now you can have a kid come to school for a year and play basketball and he doesn't even have to go to class," Knight said Monday during the Big 12 coaches call. "He certainly doesn't have to go to class the second semester. I'm not exactly positive about the first semester. But he would not have to attend a single class the second semester to play through the whole second semester of basketball.

"That, I think, has a tremendous effect on the integrity of college sports."

Knight said he would never have recruited Durant, although he doesn't blame Texas coach Rick Barnes for doing so. "I don't fault those that have, because it's within the rules," Knight said. "But the rules are just ridiculous, the way the thing is set up."

"It's just a tremendous disservice, the way that it's structured, to the integrity of college sports."

The top-ranked Florida Gators finally fell into a hole they couldn't dig themselves out of Saturday.

Derrick Byars and Shan Foster each scored 24 points, and Vanderbilt snapped the nation's longest winning streak by upsetting the Gators 83-70.

Florida had won 17 straight games and needed a victory to clinch at least a share of the Southeastern Conference's Eastern Division and the overall league title. They also had won seven straight against the Commodores.
