I agree with you on that laser that shot from his arm in the first half. I couldn't believe how fast he got rid of the ball, or how fast it shot down the field. Impressive.
My impression of him from that game is that he just seemed a little too jacked up. At least at first.
One thing I noted is that, on the first few drives, many of his throws involved pump fakes, play actions, roll outs, or some other motion to initially distract the defense. On those plays, he really seemed too anxious. Later in the half, they just had him do mostly straight drop backs, and he appeared much more comfortable.
My thought is that they should just let this kid get comfortable in the pocket before making him do all those little trick-play thingies. Which I think will be very effective, but I'd slow it down a bit right now.
