i watched the interview and the thing I came away with is his intel of the game
I think he could become a good Div 1 QB given some supporting cast
I don't watch film a lot so I don't know about his arm strength. A smart QB has a lot of pluses. Good news that Caleb has 2 more seasons in front of him. I think the key on offense will be the Big guys as do most of the other folks on this board.
