I have watched Peyton Manning played both in snowing and cold conditions. This year against the Tennessee Titans the weather was a frigid 18 degrees and Manning had no problems chucking the ball over place. Finishing the game with 397 yards and 4 Touch down passes. I have also seen him play against the Broncos in snowing conditions in 2002 and beat them 23-20. That 2002 Broncos defense was a top 6 D overall. Peyton has not played in a dome in over 2 years so he's already use to the element, if there's no wind, the Broncos will continue to do what they have done all year.
The Patriots team that Manning lost to twice in snowing condition are easily better than this Seahawks team, since they did win the Superbowl both times after beating manning.
