Todd Haley was fired by the Kansas City Chiefs on Monda after winning a division title less than a year ago.

KANSAS CITY, Mo — Todd Haley took a floundering Kansas City Chiefs franchise to an AFC West title. Tony Sparano led the Miami Dolphins to the top of the AFC East under even more dire circumstances.

Both became examples of the fleeting nature of NFL success on Monday.

The Chiefs fired Haley less than a year removed from their division title, after a 5-8 start marked by devastating injuries and discouraging blowouts, while the Dolphins parted with Sparano amid a miserable 4-9 start that included a frustrating loss to Philadelphia on Sunday.

“The results speak for themselves,” Dolphins owner Stephen Ross said at a hastily called news conference. “We’re looking to becoming a winning organization, and I thought this was the best time to make the change and let us go in a direction that will allow us to become that.”

The same lines were delivered in Kansas City, where friction between Haley and general manager Scott Pioli finally reached the boiling point. The Chiefs were penalized 11 times for 128 yards in a 37-10 loss to the Jets on Sunday, with Haley getting a 15-yarder for unsportsmanlike conduct.

“Timing in these situations is always difficult. There never seems to be a right time,” Chiefs Chairman and CEO Clark Hunt said at a news conference. “We just felt the inconsistent play the team has experienced throughout the season, including yesterday, made today the right day to do it.”

With Jacksonville having fired Jack Del Rio on Nov. 29, three franchises are now looking for a coach. Former coaches Jeff Fisher, Jon Gruden and Bill Cowher already have been connected to each of the openings, though decisions likely won’t be made until the end of the season.

Todd Bowles will coach the Dolphins on an interim basis, while Romeo Crennel will lead the Chiefs.
