Fallacy? Nope.
What did he win without Brady? Unless he proves he can win without Brady, it's not a fallacy at all Rob.
He was very good. Good? Nope. Very good.
You can maintain whatever you want, but none of your facts can prove anything whatsoever.
It's a fallacy because in a couple of Super Bowls (the first and last wins) the defense was spectacular and many other QBs could have won those games.
I disagree with Rob about 2003. That was the 3rd greatest SB performance by a QB in history, at the time. Our defense broke down and was like a sieve from about the 2 minute warning of the fist half through the end of the game.
I actually think this is the game that cemented Brady into elite status. He played out of his mind, and without him, we don't win.
But 2001 & 2018 had a huge healthy load of Belichick's D design. It was the Rams both times but look at what those Ram teams did on offense in prior games:
2018: 26, 30, 48, 31, 23, 15, 30, 54, 36, 35, 29, 39, 23, 33, 38, 35, 34, 33. The Patriots held this team to 3 points.
2001: 29, 45, 31, 42, 38, 34, 27, 35, 17, 24, 48, 31, 34, 15, 35, 42, 30, 20. The Patriots held them to 17 points.
Add the points per game together for both Rams teams: average of 65 per game. The Patriots Ds held them to 20 points total. Less than a third of what they were able to do against the rest of the league.
The way I break down the Super Bowls (and only the Super Bowls) is like this:
Great D: 2001, 2004, 2007, 2018
Great play by Brady: 2003, 2004, 2011, 2014, 2016, 2017.
Not great play by D: 2003, 2011, 2016, 2017.
Not great play by Brady: 2007, 2018.
Young Brady, did what was needed: 2001
But this doesn't really take into account the fact that Brady played great in the 2018 AFC playoffs, or that in some of the games that preceded Brady's great SB performances, Brady was off (remember when he apologized to the fans, "Sorry I sucked today!"?), or the Titans game in 2003.
This is why I was only looking at the Super Bowls. In almost every season, BB and Brady operated with a kind of ying and yang. the D came through when Brady had a bad game, and the O came through when the D had a bad game.
