Sunday, underdogs thrived during a compelling day of NFL football.

The Baltimore Ravens were a seven-point underdog at New England, losing 23-20, when kicker Billy Cundiff shanked a short field goal on the last play of the game. 

San Francisco was a two-point favorite over the Giants, but lost 20-17 in overtime, due to the misadventures of backup punt returner Kyle Williams.

Both games ended very dramatically, setting up a Super Bowl XLII rematch.

Sunday marked a great day of pro football, unless your name is Cundiff or Williams.
