How? I can buy winning it in 2020 and a great comeback effort vs the Rams in 2021 but an 8-9 season and a woeful playoff performance did not help him. Again, his legacy as the GOAT was already secure.
You could actually argue he couldn't over come horrible coaching and needs good coaching to maximize his abilty.
Well, I guess Brady also couldn't overcome coaching in 2002, 2006, 2007, 2009, 2010, 2011, 2012, 2013, 2015, 2017 & 2019. Because apparently every season he didn't win the Super Bowl he needed better coaching to maximize his ability but didn't get it.
This comes up all the time... a season is a failure for Brady because it didn't end with another Super Bowl ring. He has 3 more than any other player and 1 more than every franchise in the NFL. He won his 7th Super Bowl at age 43. What more could he have possibly done to prove himself? He's the GOAT and there's no debate about it until another quarterback reaches 7 rings. Especially not Mahomes who's forever down 0-2 to Brady in their most meaningful matchups.
But to answer your question... how did 2022 enhance Brady's legacy?:
NFL single season record pass attempts
NFL single season record pass completions
NFL record 19th division title
NFL record 20th postseason appearance
NFL record career game-winning drives (58)
NFL record career fourth quarter comebacks (46)
Brady's lost some mobility in the pocket, that was apparent this season, but his arm strength is there, he still has full command of the game (he excelled in no huddle and 4th quarter passing), and he can still light it up (e.g. week 17 vs CAR). He can still play and would be successful in the right situation next season (at age 46 which is ridiculous).
