Nice try... that's just a polished up version of "Brady's a game manager." So obviously you're still understating it because of course you're leaving out the clutchness, which is definitively what separates Brady from everyone else. There are a million examples throughout Brady's career but I'll point out the most obvious ones from the postseason alone:
Oakland Raiders, Divisional Round, "Snow Bowl": 4th quarter & OT stats in a blizzard, comeback and GWD
St. Louis Rams, Super Bowl 36: GWD in first ever SB appearance, first year starter, SB MVP
Carolina Panthers, Super Bowl 38: 18-point 4th quarter in what had turned into a shootout, comeback, GWD, SB MVP
Baltimore Ravens, Divisional Round (2014 season): overcame two 14-point deficits, comeback and GWD (against Ravens defense)
Seattle Seahawks, Super Bowl 49: overcame 10-point 4th quarter deficit against the Legion of Boom (who obliterated Peyton Manning a year prior), comeback, GWD, SB MVP
Atlanta Falcons, Super Bowl 51: 28-3, 25 points in 4th quarter & OT, orchestrated the greatest comeback in NFL history, SB MVP
Jacksonville Jaguars, AFCCG (2017 season): Brady's most underrated comeback win, 14-point 4th quarter against the league's #2 defense (without Edelman and an ineffective Gronk)
Kansas City Chiefs, AFCCG (2018 season): withstood a 24-point 4th quarter from Mahomes, phenomenally converted three consecutive 3rd-10's in OT, became Brady's signature postseason road win as a Patriot
Los Angeles Rams, Super Bowl 53: perfectly executed GWD (amazingly his 6th GWD in his 6 SB wins with the Patriots)
Besides all that (and much more), Brady was like you tried to say, an "efficient game manger" lol. Thank you for another trip down superhero memory lane.
