5. 1989 San Francisco 49ers

When you have an offense with the names of Joe Montana, Jerry Rice, and John Taylor in it, you're going to be good. And this dynasty of the 80's were never better than in 1989 where they cruised their way to another SuperBowl win.

4. 1979 Pittsburgh Steelers

The 70's belonged to the Steelers, where they collected 4 of their 6 SuperBowl victories, and the 1979 Pittsburgh Steelers were perhaps the most potent team they put on the field. In addition to their legendary "Steel Curtain" defense, they boasted the top offense in the league in '79. Terry Bradshaw threw for 3,724 yds and 26 tds while their rushing attack led by Franco Harris, Rocky Bleier, and Sidney Thornton put up over 2000 yards.

3. 2007 New England Patriots

They were the first team in any of the major sports  in over a hundred years to start their season 18-0. They overcame the debacle of "Spygate" where they were caught videotaping opponents defensive signals. The only blemish on their perfect season came in the SuperBowl, where it took a miracle catch and a clutch drive to give the New York Giants a 17-14 last second win.

2. 1972 Miami Dolphins

You can try to bash this teams undefeated record by crying about "ease of schedule" (Their opponents had a combined winning percentage of under .400) and that they squeaked through the playoffs, barely nudging out the Pittsburgh Steelers by 4 in the Championship game (Heck, they were even considered underdogs against the Washington Redskins in the SuperBowl), but the honest truth is that they went undefeated. They avoided the hiccups that plagued the other teams on this list and the only thing keeping them out of the number one slot was the pure dominance shown by the one team ahead of them.

1. 1985 Chicago Bears

William "the Refrigerator" Perry, Walter "Sweetness" Peyton, a defense that held opponents to 198 points for the season, What didn't this team have? This team was so confident that they recorded the now famous "SuperBowl Shuffle" before the playoffs even began. They backed it un in the playoffs by blowing out there three opponents by a combined 91-10.
