That is an area for improvement I see for Stidham. Right now, he waits till the receiver is open before delivering the ball. He needs to get to where he is able to anticipate the receiver being open and get it to him before the WR is open. If he can do that, which I think he'll get there with more reps, he can exploit defenses like UGA and Bama.
Another area for improvement is hot routes and check downs rather than taking off running if his first two reads aren't there or he's under pressure. Again, I think he'll get there with more reps.
