Kyle Williams' Overtime Fumble
Kyle Williams should make this list twice after not one, but two critical gaffes on special teams in the 2012 NFC championship game. His botched punt early in the fourth quarter that nipped his knee and was recovered by the Giants was overshadowed by his game-changing fumble deep in 49ers' territory in overtime. Williams filling in for an injured Ted Ginn Jr. proved costly for San Francisco. New York's Lawrence Tynes made sure of it. (Julie Jacobson/AP Photo)
