[KC Chiefs.com] The Chiefs hired Tom McMahon as their new special teams coach, replacing Steve Hoffman, who won’t be on Romeo Crennel’s staff in 2012.

McMahon was the special teams coordinator for the Rams the past three seasons.

The Chiefs parted ways with two other assistant coaches, Richie Anderson (wide receivers) and Pat Perles (assistant offensive line).

They retained their entire defensive staff, including Anthony Pleasant (line), Gary Gibbs (linebackers) and Emmitt Thomas (secondary).

On offense, the Chiefs have retained Bill Muir (line), Jim Zorn (quarterbacks), Maurice Carthon (running backs) and Bernie Parmalee (tight ends).

Unless they shift assignments among some current assistants, they are still looking for an offensive coordinator and a wide receivers coach.
