Dynasties in professional sports these days are a dime a dozen, especially in the NFL.
On Sunday, the Kansas City Chiefs can do something no NFL team has done since the 2004 New England Patriots, repeat as Super Bowl champions.
Doing that is quite an achievement, but for KC to even get to this point once again is something we’ve rarely seen teams in this league do.
How many teams have accomplished what the Chiefs did this postseason?
A 17-10 upset victory over the top-seeded Baltimore Ravens has Andy Reid’s group on the brink of a dynasty.
Patrick Mahomes, Travis Kelce and company have helped the Chiefs win their conference for the fourth time in the past five seasons.
Few franchises have been able to achieve that historically.

From 1990 to 1993, the Buffalo Bills made it to four straight Super Bowls, losing them all.
From 2014 to 2018, Bill Belichick, Tom Brady and Rob Gronkowski helped the New England Patriots made it to four Super Bowls in five years, winning it all on three occasions.
The Chiefs are the only other NFL franchise to achieve that feat.
What do the Chiefs have in common with the the Bills and Patriots?
One thing the Bills of the 90s, the Pats of the 2010s and the Chiefs from 2019 to present have in common is their explosive offenses, while rarely losing.
Buffalo had a .765 winning percentage from 1990-93, with the second-most points-per-game (24.9).
From 2014-18, New England boasted a winning record of .775, scoring 28.2 points per game, the most in the NFL.
KC have a .759-win percentage from 2019-23, and are second in points-per-game (27.4).
What teams have made it to consecutive Super Bowls?
In the history of the Super Bowl, teams have had numerous opportunities to repeat as Super Bowl champions.
However only eight of them successfully defended their title.
The Chiefs had a chance to do that during the 2020 campaign but were beaten by Brady and the Tampa Bay Buccaneers.
While the last three teams with a chance to repeat as champions failed, the previous two clubs to win back-to-back came out of the AFC, the Pats in 2003 and 04, and the Denver Broncos in 1997 and 98.
Where do Mahomes/Reid rank among Super Bowl duos?
If the Chiefs can win a third Super Bowl since 2019, Andy Reid and Mahomes would join some exclusive company.
Only four quarterback-head coach duos have won at least three Super Bowls together, and Reid and Mahomes would draw even with Joe Montana and Bill Walsh if they can win on Sunday.
Belichick and Brady lead with six, while Chuck Noll and Terry Bradshaw have four.
How have Super Bowl head coaching rematches gone?
Rarely in the history of the Super Bowl have two coaches faced each other in the big game more than once.
Kyle Shanahan and Andy Reid will only be the fourth head coaches in the NFL to have a rematch this weekend.
No losing coach has ever won the Super rematch against the same coach.
Chuck Noll’s Steelers defeated Tom Landry’s Dallas Cowboys both times, Jimmy Johnson’s Cowboys beat Marv Levy’s Bills twice, and Tom Coughlin’s Giants defeated Bill Belichick and the Pats both times they squared off.
