4. The Immaculate Reception
This one is and always will be one of the most infamous plays in NFL history. And for good reason, because it featured a huge miss by the refs. The story went that Steelers running back Franco Harris caught a tipped ball right as it hit the ground and ran it in for a game-winning score over the Oakland Raiders. There was bound to be controversy on this one, and the NFL was years away from having instant replay to aid their cause.

But it wasn’t actually Harris’ catch that was in question. No, it was whom the ball had deflected off. At the time, the NFL had a rule in place that said an offensive receiver couldn’t by the first player to touch a ball that had ricocheted off another offensive player. Replays of the insane play showed it hit Steeler Frenchy Fuqua and that Harris’ reception would have never been legal.
