The Buffalo Bills are the only team in NFL history with four consecutive Super Bowl appearances but have an agonizing past.

As the Chiefs often do under defensive coordinator Steve Spagnuolo, they brought a heavy blitz, and Allen had to backpedal away from defenders. He threw up a wobbly prayer deep downfield, and it was nearly answered by tight end Dalton Kincaid, who just missed hauling in the heave and keeping the Bills' comeback hopes alive.

The Chiefs advanced Sunday night and now have a shot at becoming the first NFL team to win three consecutive titles in the Super Bowl era.
