2009 Steelers 24 at Chiefs 27 Overtime
The season starts to unravel on a game the Steelers should've won. Despite dominating the first half, Pittsburgh gives up a 97-yd return for a TD on the opening kickoff, then plays down to the competition in the second half.
The Steelers outgain K.C. 516-282 and own a 2-1 edge in time of possession, but a pair of 2nd half INTs (including one in the end zone that is returned 94 yds) lead to 10 points for KC and the game goes to overtime.
Roethlisberger hits 32 of 42 for 398 yds and 3 TD before taking a knee to the helmet in overtime, sidelining him with a concussion. The Steelers are forced to punt after Ben's injury and on the ensuing drive, Ike Taylor appears to intercept a Matt Cassell pass, but the ball squirts free when Taylor hits the turf.
On the next play, Cassell dumps a short pass to Chris Chambers, who finds a seam and sprints 61 yds to the Steeler 4, setting up Succop's game-winning chip shot.
