It’s an impossible task to definitively rank the greatest NFL team of all time because not everyone will agree. Whether it’s personal bias, difference of opinion or different eras of football.

But USA Today Sports gave it a shot ranking the NFL’s 100 greatest teams of all time, which included five Bears teams over the years.

It shouldn’t come as a surprise that the ’85 Bears top the list. Even if people can’t agree that they’re the definitive No. 1, they’re always near the top. And it’s easy to see why, as they were “pure dominance,” especially with arguably the best defense in NFL history.

1. 1985 Bears (won Super Bowl XX) 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 that epic 46-10 Super Bowl dismantling of New England. All told, the Bears outscored their postseason opponents 91-10.

The 1940’s Bears were a football dynasty, winning four NFL championships between 1940, 1941, 1943 and 1946. And two of those teams made USA Today’s list of the greatest teams.

33. 1940 Bears (won NFL title) The original Monsters of the Midway, using the T-formation, heralded their arrival by thrashing rival Washington 73-0 in the championship round for the biggest blowout in the NFL’s first 99 seasons.

36. 1941 Bears (won NFL title) Chicago defended its crown, winning 12 of 13 games, including playoff blowouts of the Packers and Giants by a combined score of 70-23. The ’42 Bears were statistically even better, but World War II had begun gutting the league by then.

Coming in at No. 50 were the ’34 Bears, who put together a perfect 13-0 season before ultimately losing the title game to the Giants in the infamous “Sneakers Game.”

50. 1934 Bears (lost NFL Championship Game) George Halas’ charges swept through the regular season with a 13-0 record, winning by an average of 15.4 points. Chicago lost the title to the Giants, but probably safe to put an asterisk on that one — New York, the home team, got a delivery of sneakers at halftime that allowed the G-Men to better navigate a frozen field in what became known as the “Sneakers Game.”

The ’63 Bears come in at No. 65, a team that featured star tight end Mike Ditka. These Bears beat the Packers twice to deny them a a third consecutive NFL title.

65. 1963 Bears (won NFL title) The franchise owns nine titles, but the ’85 Bears and this team have the only ones since 1946. Aside from TE Ditka, not much star power here. If you guessed their quarterback was Billy Wade, you’re more than ready for NFL “Jeopardy!”
