This is the dumbest thread ever.
A guy starts 10-0 in his playoff career, and then loses the next game on the road in one of the toughest venues in the NFL to a legitimately good team, and we're wondering whether he's "lost it".
Joe Montana started his playoff career 7-1, winning 2 Super Bowls before losing his next three playoff games. Did that blow his mystique? Was he suddenly a bad QB?
Well if the question is did Brady's performance affect his mystique, then how can the answer not be yes? He was PERFECT until last week's game. He NEVER played badly in the postseason. He had NEVER lost. As you point out, even Joe Montana, considered by most to be the greatest pressure QB ever, lost some games. Had a three-year playoff losing streak in fact. Now was it realistic to expect Brady would never lose a playoff game? Of course not, but until last week the possibility of that still remained open. Based primarily on Brady's postseason performance to date, I myself was actually starting to wonder if in fact Brady might not wind up as the greatest QB of all time. Now he's not perfect anymore. He made some bad throws, throws we've normally seen him make, and it cost his team the game. I have no reason to believe Brady's "lost it" or that he's still not the best QB in football right now, but absolutely his mystique took a hit. He can never be perfect again. Like an undefeated boxer finally losing a fight. Or how we see the 1972 Dolphins versus the 1973 Dolphins (who might have been the better team).
