The Denver Broncos scored 38 points per game this year, an NFL record, led by Peyton Manning, who also set records for most passing yards and touchdowns by a QB in a season. Next week, they line up against the Seattle Seahawks, who own the league's top defense and the fifth-best overall statistical performance of any team since 1989.

If those superlatives aren't enough to whet your appetite, consider this: The difference between the Broncos' average-points-scored and the Seahawks average-points-allowed this season is the widest in the history of the big game. It is what Chase Stuart of Football Perspective calls "the greatest offense/defense showdown in Super Bowl history."

According to Football Outsiders, Seattle has the best defense in the league against the easiest schedule in the NFL (i.e.: the worst slate of offenses) and Denver had the best offense in the league against the second-easiest slate of defenses.
