Nothing is more fluid than a college basketball roster in April.
As things stand today, John Beilein has one open scholarship to work with. In two weeks, he could have three.
Michigan big men DJ Wilson (projected in the first round by Sports Illustrated) and Moritz Wagner (projected in the first round by ESPN) both have NBA Draft decisions to make and five-star prospect Mo Bamba plans on taking his time to make his college decision. If those three decisions play out leave, leave, and some school other than Michigan then the Wolverine head coach has a real problem on his hands.
Beilein has to build his roster for next year without knowing definitively what will happen with three of his 13 available scholarships until at least May 24th (the deadline to withdraw from the NBA Draft).
