“It was my fault. It was pathetic.” Denver Broncos safety Rahim Moore, on the 70-yard touchdown pass from Baltimore’s Joe Flacco to Jacoby Jones, which tied the score at 35-35 with 31 seconds remaining in the fourth quarter of an A.F.C. divisional playoff game at Denver.

How bleak was it for the Ravens? They trailed, 35-28, and they had no timeouts remaining. One minute nine seconds remained when the Ravens got the ball at their 23. Any passing play or running play that ended in the field of play would have resulted in a large chunk of time being run off the clock. At one point in the final two minutes, according to the AdvancedNFLstats.com probability graph for the game, Baltimore had only a one percent chance of winning the game.

After an incompletion on first down, Flacco slid to the ground after a 7-yard gain, setting up a third-and-3 that won’t soon be forgotten.

Flacco’s 70-yarder to Jones with 31 seconds remaining will carve its own place in N.F.L. playoff lore.
