It was asked on a sports show yesterday. If Brady has a Peyton Manning like decline in 2022, should it be held against him? My answer is unequivocally NO. The fall may or may not happen. But he's 45. He's proven he's the GOAT. Eventually everyone hits father time. Peyton Manning looked like an MVP in 2014. Then...everything fell apart. It happened suddenly. There were no signs of the decline beforehand.
Will it be held against him? Yep. Because guys like Parker, Sharpe, and others hate him. They will use any excuse to bash him.
I also don't buy into the theory that Brady's legacy takes a hit if he gets to and loses another SB. In order to lose a SB, it means you would've had to beat 2 (Or 3) great teams along the way. But a SB is always a toss up. So much involved like luck, injuries, coaching blunders etc. I also don't buy into this QB vs that QB in SB's. QB's face off against the opposing defense. They aren't on the field at the same time. Drew Brees beat Peyton Manning in a SB. So. Manning is at worst top 3 all time. Brees is barely top 10. Joe Burrow is a better QB than Stafford.
One of my top ten favorite movies is Dark Knight rises. Everything was great. I just didn't like the ending. But a not so good ending doesn't erase the previous 2 hours of enjoyment.
