If Burke decides to go pro, is there any possibility that CB might change his mind and stay with Michigan? It seems like his main gripe was playing time (somewhat understandable if he thought he was going to be relegated to 5-7 minutes a game behind Burke for his whole career), but if if Burke left CB would seem to be the near-undisputed starting PG for 2012-13.
Is there any precedent for a player announcing he's transferring and then changing his mind? Would JB take him back? Should he? The conventional wisdom is obviously "once he's gone, he's gone" but I wonder if this particular situation might warrant an exception.
