my personal opinion, a lot of these guys unless they develop pristine technique early, have habits that are hard to break unless they really work their asses off in the pros like a Brady type.I saw a couple games worth of tape on him. He was very erratic. Did make some NFL level throws but they were mixed in with some truly awful throws as well. Moved alright but not someone who has notable lateral quickness, seemed a bit stiff in the lower body. Inconsistent footwork as you might imagine from his inconsistent throws. Didn't see much off platform.
I am not someone who takes much stock in pro day/combine stuff for QBs, it's just not like what they have to do in game.
There is potential but not someone I would get really excited about.
