Manning was carried to one championship, in a postseason in which he had 3 TDs and 7 INTs, compiling a far worse QB rating than either Trent Dilfer or Brad Johnson. It was the worst postseason by a Super winning QB this century.
He has some ground to make up, to say the least.
I don't see the Patriots losing but watching Manning fall to 1-3 in Super Bowls would be an OK consolation prize if it did happen. I would be rooting for another slaughter.
