Caris LeVert officially offered his commitment to Michigan on Friday.
LeVert,a 6-foot-4, 185-pound wing, becomes the fifth member of the Wolverines' 2012 recruiting class, which includes highly touted forwards Glenn Robinson III and Mitch McGary.
Trey Burke will likely declare for the draft if Michigan advances far into the 2013 NCAA tournament.
"If I have a great season, and we go far, I probably will lean towards coming out," Burke said. "I can’t really speak on that right now, it’s too early.
"But I definitely will look into it and my coaches will help me look into it because they understand the type of situation I’m in."
Burke declined to comment on the results of the NBA's undergraduate advisory board's report.
"I just felt like it was the right decision for me to make," Burke said. "After talking it over with my family, the coaching staff, we kind of pretty much just broke down the pros and cons of leaving and staying, and I felt like the right decision was to stay.
"With the recruits we have coming in, with the players that we have coming back, we have a great chance of being a Final Four, if not a National Championship team."
Cody Zeller put a hold on his NBA career mostly because he thought he wasn't quite mature enough for the pros.
“It’s a tough process. I mean, it’s a lot of money,” said Zeller of his decision to return for his sophomore year at Indiana. “I’m just not ready to grow up yet. Paying rent, getting a house, becoming an adult — I’m not ready for all that. I’m enjoying my college career, on and off the court. I’m definitely happy to be here.”
Zeller was projected as a lottery pick in the June draft.
Amile Jefferson hopes to make his final decision by next week.
“It’s been tough,” Jefferson said. “We’re trying to set a date now. Hopefully by next week, I can finally make a decision…I need that comfort level, when I just know.”
Jefferson is considering Kentucky, Duke, Ohio State, North Carolina State and Villanova.
Amedeo Della Valle signed a letter of intent with Ohio State.
Delle Valle, a 6-foot-4 sharpshooter out of Las Vegas Findlay Prep, chose the Buckeyes over Texas A&M and Arizona.
Ohio State has three scholarships available for next season and is known to be targeting two freshman transfers from the SEC, power forward Anthony Gill and wing forward Rodney Hood.
