I can name one that I feel performed better
Cam Newton.
First time coach Ron Rivera
Previous year 2-14 team is last in passing yards with 50 sacks given up.
Newton's escape ability reduced that a bit to just under 40 per game over his first 4 years which is bad pass protection.
4 year stat comparison is really close with both players have slight edges in different areas.

I give Newton the edge for the 21 more TD's produced as well as the Pro Bowl selections during that time.
