The 2019 San Francisco 49ers and Kansas City Chiefs will become the 107th and 108th Super Bowl participants. Through the years, there have been several dominant squads, some that caught lightning in a bottle and others seemingly poised for greatness that ultimately fell short. 

With that in mind as Super Bowl LIV approaches, here are what I believe to be the 54 greatest teams to play on Super Sunday ... and not all of them won:

1. 1985 Bears (won Super Bowl XX): Pure dominance. Their 15 regular-season wins came by an average of 18.1 points. The defense collected 64 sacks while allowing just 12.4 points a week. Chicago shut out the Giants and Rams in the NFC playoffs before an epic 46-10 Super Bowl dismantling of New England. All told, the Bears outscored their postseason opponents 91-10. Sure, it would have been nice to see a rematch with Dan Marino and the Dolphins, who handed Chicago its only loss of 1985, on Super Sunday. And maybe you'd like the best team of all time – arguably – to feature a more renowned quarterback than Jim McMahon. But the fact that an offense led by Walter Payton (1,551 rushing yards) was almost extraneous also illustrates just how transcendent Buddy Ryan's "46 defense" was. And a little flair should count for something, and with McMahon, Payton, Ryan, "Refrigerator" Perry, Mike Singletary, coach Mike Ditka and many others – most getting star turns with "The Super Bowl Shuffle" – the '85 Bears had character(s) in spades.
