People are trying to jump to conclusions that aren't there. It's been stated several times. Bamba won't decide until after DJ decides and if DJ decides to come back then Bamba most likely won't be committing to Michigan anyways. And if DJ leaves, then Michigan has an open scholarship.
I would be pretty disappointed if Beilein slow played Simmons while he waited several more weeks for DJ and Bamba to decide. It's still possible they could have two open scholarships. If Simmons committed somewhere else before decisions are made, then Michigan could've hypothetically been without Simmons, Wilson and Bamba. That would be highly disapponting.
So don't read so much into it. It's something that 98% of coaches would've done with the current roster makeup. Take him and sort the rest out later
