Andre Walker is playing for Xavier after spending four years at Vanderbilt.

He had a career-high 14 rebounds in Xavier's 82-70 game in Nashville.

The Musketeers held a 54-33 edge on the boards, the worst beating the Commodores have taken on the boards at home since 2002

Vanderbilt isn't the same team without Festus Ezeli, who has been out due to a suspension and recovery from a sprained knee. They lost to Xavier at home on Monday.

While not having Ezeli hurts Vanderbilt's chances to win, the absence of a true point guard who can control the offense late in games is sizable flaw.

Brad Tinsley is a good perimeter shooter, but he struggles to get Vanderbilt into their offense.

Xavier rallied from 10 points down to beat Vanderbilt by a final score of 82-70 at Vanderbilt.

Tu Holloway scored 10 of his 24 points in overtime.

"It's all cause of my backcourt main man, Tu Holloway," Mark Lyons said. "I love him because of the way he plays. (He's) a killer on the court, and he won the game for us in overtime."

Alex Poythress will announce his decision to commit to Kentucky.

Poythress, a 6-foot-7 small forward, also considered Florida, Memphis and Vanderbilt.

Poythress is rated as the 17th best recruit in the class of 2012.

Vanderbilt coach Kevin Stallings is working with John Jenkins, one of the best pure shooters in the country, to improve his defense.

“He’s moving his feet better,” Stallings said.

“He’s trying harder. He’s thinking about it more. “He was never mentally engaged with defense — ever. And he tries as hard on the defensive end now as he tries on the offensive end. That’s really saying something because that kid has to try really hard on the offensive end the way he gets covered. His effort defensively has just been phenomenal.”

Jeffrey Taylor is considered a perimeter stopper, but Jenkins has been a liability.

“It could have been better last year,” Jenkins said of his defense. “It was good at times. It was not good at times. People can say that I run around on offense a lot and it was tiring me out, but I can’t use that as an excuse. I’ve got to get down in a stance and guard somebody.”

Jenkins is currently a borderline first round pick in the 2012 NBA Draft.
