In terms of overall talent, Cam Newton arguably was at the top of this list before he ever threw a ball on the professional level. Newton was the Heisman Trophy winner in 2010 at Auburn where he turned every head with his freakish physical abilities and as a rookie, he was the AP Rookie of the Year going to the Pro Bowl and throwing for over 4,000 yards and rushing for 706 and 14 Touchdowns. This was typical of what he would do for the Panthers throughout his career as a true dual-threat Quarterback who is built like a Linebacker. Newton has rushed for over 50 Touchdowns, which is more than many Pro Bowl level Running Backs.
There should be no question that Steve Smith is the greatest Wide Receiver in Carolina Panther history, and as of this writing is the best Panther period.
