I think he's no better than fourth round material in a normal world.
He's got excellent arm strength and a very good delivery, but he's very inaccurate when he's forced to make a throw. He gets anxious when the game gets put into his hands.
He's got better than ideal size, is smart and understands football from what I hear.
He just struggles when the pressure starts to mount and he's not very accurate in the mid to deep areas of the field, especially on anything other than straight post patterns.
He's no better a prospect than someone like Osweiler or Mallet from recent drafts. A better person but a worse football player actually.
IMO, he'd make a terrific third QB running the scout team. That's his ceiling as far as I see it.
