You can read about WhatIfSports.com at the links above, but basically they've run the entire 2006 schedule through their Gigantic Statistical Warp Machine, and projected the final standings and playoff order for the upcoming season.
So. Long and short of it, they have the Seahawks beating the Steelers in Super Bowl XLI by a score of 16-10.
But, keep in mind, they also pick the Giants to win the NFC East. Maybe their computer's fan was hiccuping or something.
