No, actually you can't. We covered this before.
The 2001 Patriots team was average. In fact they were a sucky 5-13 before Brady became the starter and miraculously they morphed into a 14-3 Super Bowl winning team. The 2018 Patriots team wasn't that great either. Beating Mahomes and the Chiefs in that AFCCG on the road in OT was extremely unlikely. The Chiefs exploded for a 24-point 4th quarter too, and still lost, which is unbelievable.
I addressed this in another thread already. I believe your exact statement was Watson and Brees were the best QBs in the league (2020 and 2016 respectively) yet their teams had losing records. It's not an accurate premise. Aaron Rodgers was easily the best QB in 2020. Several other QBs had seasons on par with Watson too: Mahomes, Allen, Wilson, and even Brady... all four made the playoffs and Brady and Mahomes met in the Super Bowl. Brees was bettered by Brady, Ryan, and Rodgers in 2016... all three made the playoffs and Brady and Ryan met in the Super Bowl. You'll notice a trend of the best quarterbacks often meeting in the Super Bowl, that is unless you have an agenda to look the other way.
