The Refs did give some calls to the Broncos. As a matter of fact, those calls help moved the chain for the Broncos during the game.
How about all of the non-called PI's that should have been called against the Hawks. They were allowed to molest and mug the opposing team's WR's on about 75% of the passing plays. But then again, they were allowed to do that all season.
Their reputation influences the calls.
But no...that is not why the Hawks won. They won becuase they were the better team and because Peyton Manning is one of the greatest regualr season QB's of all time....and one of the biggest playoff choke artists of all time.
