#8. Miami Dolphins (1972)
Miami Dolphins did something in 1972 that no other team had done before or has replicated ever since. The team managed to finish their regular season with a record of 14-0. The team met the Washington Redskins in Super Bowl VII and they easily brushed them aside and finished the season 17-0. The undefeated campaign was led by players of high caliber such as Bob Griese, Earl Morrall, and Larry Csonka. The group of outstanding athletes was coached by Don Shula. Therefore, the Miami Dolphins hold the record of being the only NFL team to win the Super Bowl with a perfect season.
