Dan Marino is probably the 4/5 best QB of all time, as we know 0-1 in SB. While Brad Johnson and Trent Dilfer and Jim McMahan are SB champs. So just how important is winning the biggie to a QB's legacy? Philip Rivers Warren Moon Fran Tarkenton Dan Fouts Jim Kelly Tony Romo Matt Ryan are on a par with Eli Manning Phil Simms Joe Namath Terry Bradshaw Len Dawson Doug Williams Bart Starr All SB champs. Nobody thinks Jim McMahan was a great QB, he was no Dan Fouts. Fouts had one of the greatest offenses we have seen, three 1000 yard receivers and a stud RB, but a defense Alabama would have put 30 on. McMahan had the great Walter Payton and a D that had five future HOFers and a Mad Dog on it. So just how much credit do we give a QB for SB success or failure? The game Doug Williams had was incredible so, hmmmm?
