Maybe for Cooney? His career has been derailed big-time by his serious knee injury, as has Scully's, with his dodgy knee, Kruezer, as you said, Patton has now had two knee reco's, Marc Murphy had a knee injury slow him down just as he was starting to become really elite a couple of years ago, although that wasn't as bad as the others.I think you could say that for Kruezer....maybe for Clooney. Who else?
