Patrick Peterson's OT 99-yard punt-return TD

In 2011, an impressive 66.8 percent of all games (171 of 256) were within one score in the fourth quarter.

With so many close games, it's no surprise that 13 were ultimately decided in overtime, including four OT victories by the Arizona Cardinals, a single-season NFL record.

Originally in effect for the 2010 postseason, the new rules for modified sudden death overtime -- which have been expanded to the regular season and preseason for 2012 -- were utilized for the first time during the 2011 postseason. Denver beat Pittsburgh in the AFC Wild Card round in the shortest overtime game in NFL history (11 seconds) and the New York Giants outlasted San Francisco in overtime of the NFC Championship Game en route to a Super Bowl XLVI championship.

From rookie Patrick Peterson's game-clinching 99-yard punt-return touchdown in the Cardinals' 19-13 overtime decision against the Rams in November to Demaryius Thomas' 80-yard game-winning touchdown catch in the Broncos' 29-23 overtime playoff victory against the Steelers, 2011 was full of exciting OT action.
