He destoried AJ Hawk though (during Hawk's INT runback last season)
He is a good running back but I didn't really think he was a heisman canidate especially since Texas has a couple of runningbacks playing at once (Well Taylor left the team after getting caught with a backpack full of weed so that'll open up some doors) Maybe he could end up as one, but I just can't see him being one of the "Preseason Favorites" for it that's all.
Charles runs over Nate Salley at like the 1 minute mark in this video as well -
