His stats don't matter. It's how stats come that means everything. Carr is never winning a super bowl not because of his stats. But because he doesn't dissect defenses well and put the players around him in positions to succeed. He has to rely on the players around him to out play their opponent and put him in position to succeed. The exact opposite of most QB's who win the super bowl in the last decade.
A better question to ask. Does Rattler elevate the players around him, or do the players around him, elevate him?
