Saying Manning's "flaw" was he couldn't win big games, and then saying Brady is the GOAT because he can, is to forget, or outright dismiss, the fact that Manning was 3-1 against Brady in the AFC Championship Game, the BIGGEST game Manning and Brady could have possibly faced each other head to head, on the field. Again, for those in the back, the BIGGEST game they could play each other in, head to head, Manning was 3-1 against Brady.
But, he was 0-3 (not 0-4) against UF, so let's always talk about that. Knock yourselves out.
