It was a dilemma no other NFL team had ever faced: How do you improve on perfection? The 1972 Miami Dolphins became the first team in pro football history to finish a season unbeaten, going 17-0 with a Super Bowl title. That kind of success could make anyone complacent. But head coach Don Shula was not going to allow it. He believed his Dolphins could perform even better. Still, the 1973 Dolphins did not match the same level of success as the season prior. They exceeded it, according to Shula. In Super Bowl VIII, Miami pummeled the Minnesota Vikings for it's second-straight world championship. I think that were a better football team than we were a year ago at this time, said Shula afterward. I think us going back-to-back in Super Bowls is more meaningful.
