Harris ran for 12,120 yards and won four Super Bowl rings with the Steelers in the 1970s, a dynasty that began in earnest when Harris decided to keep running during a last-second heave by Pittsburgh quarterback Terry Bradshaw in a playoff game against Oakland in 1972.
With the Steelers trailing 7-6 and facing fourth-and-10 from its own 40-yard line and 22 seconds remaining in the fourth quarter, Bradshaw drifted back and threw deep to running back John "Frenchy" Fuqua. Fuqua and Oakland defensive back Jack Tatum collided, sending the ball careening back toward midfield in the direction of Harris.
