The Unbeaten Dolphins (1972)
Miami had an incredible undefeated season in 1972 but we don’t talk about the fine margins that made this happen. One game against the Vikings saw them receive a controversial call that won them the game. If the referee didn’t fail at that moment we’d never talked about this Dolphins’ team.
Bob Lurtesma received a roughing the pass call after he tackled Bob Griese. However, viewers protested that it was fair and that he didn’t make excessive contact. Unfortunately for Lurtesma, it didn’t matter because the referee stuck by his decision, and the Dolphins won the game (via NFL.com).
