Jamies had a "nearsightedness" issue he had taken care of

He was constantly under pressure and was sacked 47 times last year. Pressure on a QB can make them do questionable things.
I always felt one of the most surefire ways to wreck a QB’s development is to bring him into the league under a bad O-line.

Hard to develop good habits when you are running for your life or getting beat up all game.
