Dan Marino is far better than a lot of SB winning QB's. Terry Bradshaws stats totally suck. How many INT's did Namath have in his career? Johnny Unitas was far better than Bart Starr. Fran Tarkenton and Jim Kelly were great QB's. Don't put everything into SB success.
Manning had a fantastic career, all those NFL records, all those awards, Pro Bowls, MVPs, All Pros. We don't ignore all that and he did it for a long long time.
14 pro bowls/7 first team All Pro/5 MVPs/2 SB wins
Brady, Montana, Peyton......then we can debate 4th.
