Basically what it seems like is that if Brady, Peyton, Brees, or Rodgers wins the Super Bowl, then we can praise them with all the adulation in the world. If another QB wins the SB, then it was the team who carried them.
Meanwhile Brady hasn't won since 2004 when he last had an elite defense. Peyton only won 1 SB, and that year his defense absolutely carried for most of the postseason. Brees hasn't won again since his defense got shittier, and neither has Rodgers.
