It probably shouldn't have been too surprising that Willis McGahee went pro despite his injured knee. The only reason I'm surprised is that few people considered the possibility when he got hurt in the first place. The only person to say anything about it was Jason Whitlock, and it made plenty of sense at the time. The early money may not be there right away, but getting a third- or fourth-round contract, going on IR and getting proper treatment from pro trainers will mean something in the long run. The question is when a team is willing to make the move on a running back with a known knee injury. Much smaller injuries longer ago have killed some players' draft status in the past.
