He has some tangibles that you cannot teach. Long arms with big hands. He catches the ball away from his body. He has hands that are good at securing the ball. He is not quick, he is slow to gain speed, but once he starts to accelerate he keeps accelerating. This type of speed is very difficult to cover deep.
He needs some seasoning and some time to learn the system, but he may surprise and play early because he can and does catch most everything thrown his way. If he can block well, he will see the field early if not, he will take some time before he shows up on game day.
