As
@thunderpimp91 said, he seemed to understand what was going on & getting thru his progressions (maybe a touch slow though), he kept his focus downfield, has a natural, easy throwing motion & he didn't turn it over.
With some reps I could see him getting thru the progressions quicker & being more relaxed which should help him get the balls more on target.
As for his natural running ability, he used it well but wasn't looking to run just for the sake of running. So, that shows he has the discipline to not just take the easy yards with his legs but force himself to navigate the pocket & deliver the ball to playmakers.
We will never know, but it feels to me that getting him experience without the pressure of being a high draft pick and he might have been a good QB by this time of his life.
