PFF - have y'all seen this
You put me in a weird position because I like Winston.
But Carr has a better Career Completion Percentage and a better winning Percentage.
Winston has had significantly better talent surrounding him on offense.
Even though Carr has 2100 more attempts and 14000 more yards, and 80 more touchdowns, they have virtually the same number of interceptions.
So despite all your stats, the traditional stats QBs are measured in: Completion Percent, TD:INT Ratio 4th Comeback drives, and Winning Percentage, Carr tops Winston in all of them.
