willis mcgahee was one of the best running back prospects ever, and was such an explosive player in college. His injury made him a shell of what he was.
He had a long career but he could have been a hall of famer.
make no mistake acl is one of the most serious injuries an athlete can sustain.
It really depends on how badly it is torn... the fact Hextall says he could be back by year end makes me think it is 'not too bad' a tear.
Mine was a partial tear... and after 4 months I could pretty much do everything to the level I could before with little discomfort of the knee itself, all discomfort went after like 7 months.
The only lasting damage is actually to my hip on that side... as I came back to quickly (I was fighting for a roster spot on an U17 national team... silly really as I was only ever good enough before injury to creep into the 30 man squad as an afterthought... never for the 18 man cut!) and 'cheated' on a lot of activity involving that leg for a while, kind of 'favouring' it in a way for a few months as I was scared it would go again... which caused hip problems due to the mechanics being all out of whack! But that would not have happened with better trainers and top medical care.
The knee now is perfect as can be... no complaints for 7 years.
