It always goes back to before he was even drafted. There was really no in between on how people felt about him. They either liked him, or they hated him. It doesn't look like that will ever change throughout his career. So no matter what he accomplishes, some people will never see it as enough, or look to diminish it in some way. It's sad that some people are like that, especially actual fans.
Plenty of people in the middle (as myself).
Cam has the potential and talent to be a top 5 QB in the league. He has shown flashes.
With that said, he still has a lot to improve on ie consistency, footwork, decision making, etc.
