Even without checking their standings or depth chart, I can say with confidence that Seattle is not likely to win the Super Bowl.
For that matter, neither are Philadelphia, Baltimore, Arizona, or Atlanta. In fact, in 46 Super Bowl match-ups from 1967 to 2012, only once has a football team named for a bird emerged victorious in the championship game. The Baltimore Ravens crushed my beloved New York Giants in Super Bowl XXXV (2001) to become footballs finest feathered franchise. Teams named for Homo sapiens just do better in this game. In an astonishing 33 of 46 contests, an organization named for a meat (not cheese) packer, chieftain, cowpoke, steel worker, indigenous American, gold miner, U.S. nationalist, servant of a deity, oversized individual, or some species of pirate has won it all.
