I'm a Giants fan and I have to say it sucks having him in the division.
I wouldn't worry too much, I'm not the type to wish ill on someone, but he seems to be injury prone. he's already torn an ACL and now this, and he's what...20 years old? he can't keep running like that and survive.
Reminds me of Randall Cunningham, except that RC had five great years in the league before he suffered a major injury, this kid didn't make it out of his first year. again, not hoping for bad things but looking at it purely on the face of it.
I would bet against him coming back from this and running up and down the field for the next decade and never seriously getting hurt again, he's going to have to change his game. Look at Michael Vick, he's constantly getting hurt. And he's a powerful, compact guy who isn't all limbs like RG3, guys like that get laid out and crushed.
