  1. 1989 San Francisco 49ers

Bill Walsh had walked away from the 49ers after they had won the Super Bowl following the 1988 season, and many thought that the team would lose its edge with mild-mannered George Seifert taking over as head coach.

However, Seifert proved to be the perfect replacement for Walsh. He was not as demanding or detail-oriented as Walsh, and the players loved that they seemingly had more freedom. Seifert put his signature on the team, and the Niners played with increased efficiency all season and dominated with a 14-2 record.

The Niners were at their best in the postseason, as they dominated the Minnesota Vikings and Los Angeles Rams in the playoffs before a record-setting performance by Joe Montana and the offense in the Super Bowl as San Francisco rolled to a 55-10 victory over Denver.
