No denying that Peyton is by far the most talented QB in the NFL, but he's got to step it up in the postseason unlike he has before, since that's what matters in the end.
I'm not saying he won't though.
Seems I remember that Dan Marino never won a Super Bowl game.
So the Super Bowl is not everything in regards to personal performance.
With a Super Bowl win, the quarterback can't do it alone; it takes the entire team playing at their best.
I'm sure Manning will keep giving 100%. Hopefully, the rest of the team will play at that level too.
