Regular-Season Record: 226-177 (.561)

Postseason Appearances: 13

Super Bowls: four appearances, three titles

For the most recent quarter of the past quarter century, the Kansas City Chiefs have been indisputably the most successful franchise.

In the six completed seasons since handing the reins to Patrick Mahomes, they’ve won three Super Bowls, played in a fourth and lost in overtime of the AFC Championship Game in the other two years.

While the NBA has produced six different champions, the Chiefs either won or almost won six titles in a row.

As such, there might be some head scratching over the fact that this recent juggernaut only landed at No. 7.

However, the pre-Andy Reid years from 1999 to 2012 still counted, and were decidedly not great.

Kansas City went a combined 98-126 during those 14 seasons, plus an 0-3 record in the postseason. In fact, before Reid led them to a win in the wild-card round in 2015, the Chiefs had lost eight consecutive postseason games, dating back to the 1993 AFC Championship against the Buffalo Bills.

Priest Holmes’ three healthy seasons (2001-03) with the Chiefs were a whole heck of a lot of fun to watch, but it was otherwise rough sledding—particularly in the 2007-12 timeframe, when Herm Edwards, Todd Haley and Romeo Crennel each had painful, brief stints as head coach.

Since scooping up The Walrus after the Eagles sent him packing, though, they’ve reeled off 12 consecutive winning seasons, including the current one with its 9-0 start.

Quite the 180 from annual doormat to AFC West juggernaut.
