Carthon joins Haley's staff in Kansas City

Posted by ESPN.com's Bill Williamson

New Kansas City coach Todd Haley just added to his staff by adding a third coach he worked with in Arizona, Cardinals' running backs coach Maurice Carthon. Meanwhile, the team officially announced Chan Gailey will remain as offensive coordinator.

Carthon will be Haley's assistant head coach. Haley was Arizona's offensive coordinator and Carthon was the running backs coach. It wouldn't be a surprise if Carthon also worked with the running backs. Earlier this week, Haley brought in former Arizona defensive coordinator Clancy Pendergast, who was fired this month, will be a defensive assistant and former Arizona assistant Dedric Ward who will coach the receivers.

Thus, Haley's top offensive assistants will be Carthon and Gailey, who was the team's offensive coordinator under former head coach Herm Edwards in 2008. It wouldn't be a surprise if Haley, known as one of the more aggressive offensive coaches in the league, calls his own plays.

With Gailey retained, the Chiefs can keep some continuity to an offense that was solid at times last season. If the team decides to stick with quarterback Tyler Thigpen, who started in the second half of the season, there will be some familiarity between him and Gailey.

Gailey often held the reins on Thigpen so it will be interesting to see if Haley unleashes him some if Thigpen is brought back as the starter.

Kansas City also disclosed the responsibility of some of the coaches it hired earlier this week. They are: Bob Bicknell (tight ends), Joe D'Alessandris (assistant offensive line), Steve Hoffman (special teams) and Bill Muir (offensive line).
