Also hired were Bill Muir, who was the offensive coordinator and the offensive line coach for the Tampa Bay Buccaneers, and Joel Collier, Pat Perles, Steve Hoffman and Dedric Ward.
Besides Gailey, those assistants retained from former head coach Herman Edwards' staff were Bob Bicknell, Joe D'Alessandris, Tim Krumrie, Brent Salazar and Cedric Smith.
General manager Scott Pioli and Haley were hired after the Chiefs went 2-14 last season, the worst record in franchise history.
Gailey, a former head coach for the Dallas Cowboys, was forced to reconfigure the Chiefs' offense because of season-ending injuries to the team's top two quarterbacks. He switched to a quasi-spread offense to fit the talents of Tyler Thigpen, a third-team quarterback. Thigpen managed only one victory, but the offense did move the ball.
Haley, the offensive coordinator for the Arizona Cardinals last season, might want to call his own plays, although that hasn't been announced.
Perles spent the past six seasons at North Dakota State and was offensive coordinator the past four years. Ward was on Haley's offensive staff with the Cardinals the past two years.
