One of the things that stands out to me is his spacing and footwork. He seems to have a knack for buying time by seeing where on the field he'll have the most time to throw. He's slippery and his release is really quick so he can wait til a guy is almost in his face and still put the ball where the WR can catch it. While it's CFB, those characteristics he shows are going to be really important in the pros. His arm is unquestionably elite.
The rest, we'll have to wait and see how he does.
