Define "big game".
400 yards, 80% completions, 2 TD's, no picks two weeks ago in the AFC Championship. Is that a "big game"?
Seems like you're the one ignoring "big games" if you say he always chokes. He's played well in many big games. You don't play in 23 postseason games by playing badly in "big games".
Of course, what you mean to say, is Super Bowls. Your entire stance is based on Super Bowls. If that's the kind of analysis you like to do, ok. To me that's being lazy and surface level.
Nothing he did tonight was going to change my mind on Manning. He's 37 and is what he is. Bad game, good game, great game. He's the best regular season QB ever. He's won a SB and played in two others. Not the best postseason QB, not even close really, but he's been good enough that combined with his overall play, to me that makes him the best.
I'd rather take my chances overrating 240 games than 23, or 3, or 2. The 240 games tell me all I need to know, the three Super Bowls simply close the case for me.
