I also think you're forgetting that Can is putting up his best passing numbers this year, so even if you believe he has had a clean pocket, then you should have nothing to complain about.
I am not blaming Newton for the start this year. Not at all. Newton is what he is. But since you bring up numbers, here they are:
Cam Newton is
26th in completion percentage
22nd in yards per attempt
21st in NFL passer rating
18th in yards per game and
17th in total QBR
There is plenty of finger pointing and hyperbole thrown around on this forum about other parts of the team, from the owner, GM and coaches to the offensive line, defensive line, defensive backs, linebackers and even running backs and receivers.
Guess what: Cam Newton has not been that great either.
