Folks, he showed up for every game as a freshman in the SEC and ended up carrying the bulk of the running load before midpoint in the season including the bowl game. Injury prone is not physically able to answer the bell during the season(s). Hurd answered every bell on our 2013 schedule with a very suspect OL, therefore per my standard was very far removed from being classified as injury prone.
Not questioning the kids toughness, he's a beast. But factually speaking, he left HS with a shoulder injury requiring surgery, he played 1 series vs UTC because many thought he had reinjured the shoulder, he didn't finish the Vandy game due to a concussion (took a helmet to the jaw iirc), and he didn't participate in any live contact this Spring due to a shoulder injury.
I'm certainly not questioning how tough Jalen is, that'd be ridiculous, kid's a warrior. But even the toughest of players can suffer frequent injuries or a recurrence of the same nagging injury, through no fault of their own...to this point, that seems to be the case with Jalen IMHO.
