I hope we offer and get him, but that is my main concern as well. That can improve some with strength and conditioning. You don't have to have a howitzer attached to your shoulder, but you need to be able to make all the throws. He would be an early redshirt/depth piece for sure. I know this might be sacrilege around here, but Peyton didn't have a cannon. It was strong enough to make all the throws, but nowhere near the strongest arm. Milton is a freaking unicorn, but Hooker has enough strength to get the job done. Success and having arm strength for QB isn't being able to throw the ball 80 yards. It is being able to fire a slant in a tight window before the DB can break. It is gunning an out or a comeback from the opposite hash on a rope without the ball having to loop out there. Arm strength is timing with your WR.
He has enough intangibles/work ethic/knowledge/size for him to be a take for me, and I hope we recruit him.
