CB Donovan Warren
The buzz: Warren was one of the few players in Michigan's back seven on defense who played well this past season. His decision to turn pro leaves Michigan painfully thin at cornerback. Troy Woolfolk began last season at strong safety, then was moved to corner. Woolfolk's best position is strong safety. If he moves back to that spot, it seems likely that sophomores J.T. Turner and J.T. Floyd will be the leading candidates at corner. Turner played in one game this past season; Floyd played in nine games and started two. Depth is nonexistent, and a position change or two could be coming for that reason. It's likely two or three freshman corners play this fall. There are rumblings that former starting corner Boubacar Cissoko, who was booted from the team in midseason, could work his way back onto the roster. His return would be big.
The bottom line: Warren's departure is huge -- maybe as big as anyone's on this list. Michigan is in deep trouble at corner.
No idea why he thinks Boo Boo has a chance to get back on?
