Not to wash Cam's hands completely clean, and maybe I'm ignorant on the job description, but isn't throwing mechanics training basic QB coaching?
I know Dorsey's new to the gig, but imagine you're him. You have a talented quarterback and the one major flaw in his game is he overthrows receivers or keeps the ball too high often. He actually play his best when he's forced to call plays himself at the end of the game and is short on time. What exactly are you doing as QB coach if Throwing Motion 101 stuff continues to be a chronic issue for your quarterback?
