The mere fact that he mentioned Cam was having trouble releasing a throw in time is tough to digest simply because Newton has one of the fastest releases in the NFL. And that's not me talking.
He's never had issues reading defenses either. Cam wasn't taking what the defense was giving him. He's a young gunslinger. That was to be expected. That, and his short game was mediocre/decent.
What do you know about grading a quarterback?
