Forget his physical performance in the second half of the ND game, what I was most impressed with was the way in which - in his first meaningful action in a Syracuse uniform - he seemed to be 100% comfortable running the offense. He was getting guys lined up in the right spots, making pre-snap reads/adjustments and just seemed to be loose and having a little fun.
That type of stuff tells me that he's a real student of the game and makes good use of practice time and his time on the sidelines. It could all come crashing back to earth if he's forced into making his first career start at Pitt on Saturday, but my first impressions are positive.
