Watching him play throughout Jr High and HS, he really only struggled throwing the ball when he was pressured. He threw it up for grabs at times when he was.
He'll go through growing pains like almost all young QB's, but I think he'll be very good once he settles in. I think he's similar to Max Hall in that he has fire inside, very competitve. But he's more athletic than Max was and has a stronger arm.
