right now, and it's nitpicking giving how well he's played so far, is he needs to somehow undo his instinct to spin and run backwards, taking his eyes off the field, whenever he feels pressure.
That's a habit from high school when he could outrun guys and gain 20 yards on the ground. It only sometimes works out in college, and won't work at all if he manages to go pro.
But again, he's playing so well right now, so that's just a nitpick.
