He threw 2 picks. WHO CARES?? Trust me, absolutely no one, except for you, remembers those picks. What people remember is Brady's comeback, the win, and the MVP. Brady was 14-16 for 130 yards and 2 TDs in the 4th quarter of that Super Bowl. End of story.
Brady threw a pick-six while the Falcons built their seemingly insurmountable 28-3 lead in SB 51. No one cares about that either. What people care about is Brady's comeback, the win, and the MVP. Brady was 16-21 for 196 yards and 1 TD (and 1 two-point conversion completion) in the 4th quarter of that Super Bowl. He added 5-6 for 50 yards on the game-winning TD drive in overtime.
Brady's 4th quarter/OT stats from Super Bowl's 49 and 51 (just over half a game):
35-43 (81.4%) for 376 yards and 3 TDs (0 INTs)
Let that sink into your thick skull.
