This year, the NFC and AFC Championship games were anything but boring.

Like last year, the games will be remembered by big plays and game-changing turnovers. 

Last year, in the AFC Championship, with a chance to win the game, Billy Cundiff missed a 32-yard field goal that would have propelled the Ravens to the Super Bowl. In the NFC Championship, Kyle Williams dropped a punt that would have essentially propelled the 49ers to the Super Bowl if they would have been able to waste the clock.

But the past is the past, and both teams came to play on Sunday seeking redemption.

That doesn't mean there weren't monumental screw-ups this year.

Who is responsible for their teams loss this year? Who are this year's Billy Cundiff and Kyle Williams?
