From the two videos, all I can tell is that he's quick, runs well, has a fairly live arm, and does reasonably well with the short-to-medium throws. His longer-range accuracy is a little suspect, and he makes some head scratching throws every now and then.
It will take him time to become comfortable in the offense, and he'll turn the ball over a few times. But he'll probably do well enough to make the games interesting, although unlikely we win many unless the defense really picks it up.
