The one that sticks out is pass attempts. Through four games this year, Newton has thrown 56 fewer than at the same point last year. So far this year, the Panthers are running 11 fewer offensive plays than their opponents (57.25 to 68.25); last year, they had 15 more plays per game than their opponents through the first four games. This split is unsustainable. It can result from both positive and negative factors – turnovers and special teams errors giving opponent shorter field versus longer, third down rates, defense giving up big plays versus long drives, etc.
Yes, Newton fumbled at a key moment in the last game against Atlanta. Descriptively, we can say he is slumping, if that means anything. Predictively, his numbers look better. Interceptions are rare and volatile, and his rushing numbers, completion percentage, yards per attempt and touchdown rate are better than the same point last year. The difference is how we perceive him.
