I hope it's shitty weather in New York. I also anticipate another close Super Bowl. A great defense with a clock control offense against a dynamic offense with a suspect defense. Last few offenses of similarity to Denver were challenged by opposing defenses (2011 Pats, 2010 Green Bay, 2007 Pats) with those games all decided by six points or less. The 2009 matchup between two high-powered offenses, Saints/Colts, was a 14-pt margin - though that swing came on one play - a Peyton Manning interception returned for a touchdown. Those defenses were average if memory serves, though I do recall the Saints producing an abnormal amount of turnovers (and turnovers for score) that season.
Manning's two SB appearances haven't been superb.
vs Chicago, 29-17 win; 25-38, 247, 1-1 (22 offensive points) [Probably lucky his opponent was Rex Grossman, a terrible QB, but vs a top tier defensive unit]
vs New Orleans, 17-31 loss; 31-45, 333, 1-1 [His lone mistake lost the game for his team]
