Other worries: Mitch McGary's back was hurting before the season began, and the course of back injuries is hard to predict. Many also argue that Robinson has to become more aggressive. But a significant part of U-M's success last year was precisely because he was a master at letting the game come to him. If Glenn tries to do more, the team may do less.
The biggest unknown is how it will all fit together without last year's leaders. Michigan, ranked No. 7 in the nation at season's start, could win the Big Ten, but more likely will finish second to Michigan State--which beat Kentucky in November to become No.1 in the country--or maybe third. They will make a tournament run but, given their inexperience, the Sweet Sixteen is about as good as it will get.
