Romeo Crennel has just made his first coaching staff moves as the head coach of the Kansas City Chiefs.

The team announced it has hired Tom McMahon to be the special teams coach. He spent the past three years as the special teams coach in St. Louis. Kansas City did not retain special teams coach Steve Hoffman. The Chiefs also announced wide receivers coach Richie Anderson and assistant offensive line coach Pat Perles were not retained.

The Rams were considered to have one of the better special teams in recent years.

"I am pleased to add Tom to our staff," Crennel said in a statement released by the team. “He is a diligent worker and passionate coach. It is a great addition for us."

The team’s biggest remaining hire to make is an offensive coordinator.

The Kansas City Chiefs made some more changes to their staff. None were overly surprising.

The announcement that sticks out is that former defensive coordinator Clancy Pendergast is no longer with the team. He was replaced by Romeo Crennel two weeks ago. At that time, Kansas City head coach Todd Haley said he wanted Pendergast to stay with the team in some form.

Pendergast’s unit struggled last season, but he is a solid secondary coach and the Chiefs could have benefitted from his presence on the 2010 staff.

Former tight ends coach Bob Bicknell and receiver coach Dedric Ward are officially parting from the team.

Richie Anderson was named receivers coach. He worked heavily with the unit during the season. Anthony Pleasant, a 14-year NFL defensive lineman, was named a defensive assistant. Former defensive quality control coach Pat Perles is now the assistant offensive line coach.

In his search to bring life to his anemic offense, Kansas City coach Todd Haley on Thursday made the second change to his offensive staff in less than two months.

Haley demoted receivers coach Dedric Ward and replaced him with Richie Anderson, according to the Kansas City Star. Anderson was on the Chiefs’ staff as part of a minority coaching fellowship program. Ward remains on the staff.

Prior to the season, Haley relieved offensive coordinator Chan Gailey of his duties. Haley is now the offensive coordinator of the 0-5 Chiefs.

Thursday’s move was made to spark a porous group of receivers. Cleary, Haley liked the way Anderson was working and wasn’t pleased with Ward’s progress.

Haley has to be careful. In-season assistant coaching staff changes are rare in the NFL. For two changes to happen before the sixth game is truly remarkable. Haley, an offensive coach, just can’t keep changing coaches during the season. After all, he hired Gailey and Ward.

Haley is obviously doing everything he can to improve the offense and that is admirable. But sooner or later these desperate changes are going to start reflecting poorly on him if positive results aren’t seen.
