1983 AFC Playoffs Steelers 10 at Raiders 38
The underdog Steelers seem to get off to a good start, driving 78 yds in 8 plays to the Raider 1-yd line. But on 4th down mere inches from the goal line, Chuck Noll elects to kick a FG for a 3-0 lead. I'm not saying the Steelers would've won had Noll gone for it and scored a TD... but I do view settling for a FG as the beginning of the end.
On Pittsburgh's next drive, Lester Hayes perfectly diagnoses the play, comes off his man to step in front of a Cliff Stoudt pass intended for Calvin Sweeney and races 18 yards into the end zone with his arms and the ball raised triumphantly in the air. The Steelers never recover as the Raiders extend their lead to 31-3 before the out-gunned Steelers finally cross the goal line.
