When general manager, Scott Pioli, hired Todd Haley as the head coach of the Chiefs in 2009, Haley brought in Muir as his offensive line coach. After Charlie Weis left the Chiefs following the 2010 season, the Chiefs promoted Muir and made him the offensive coordinator for the 2011 season.
Muir was given the play-calling duties for the first time in his career this past season. But Muir, Haley and quarterbacks Matt Cassel and Tyler Palko would often clash as the play call was delivered too late. This forced the Chiefs offense to waste a timeout early in a half.
When the Chiefs relieved Haley of his duties in December, Muir was able to call the plays on time in a smooth manner. However, the Chiefs offense still had a lot of room for improvement.
With Muir gone, this is an opportunity for the Chiefs to give an assistant coach a chance to prove themselves. Due to Muir's departure coming in February, the Chiefs are behind the eight ball and must move fast. At the same time, the Chiefs may not have to look far for a new offensive coordinator.
Quarterbacks coach Jim Zorn would be a viable candidate to become the next offensive coordinator of the Chiefs. While being the head coach and the offensive coordinator in Washington, Zorn was limited in finding success with the Redskins. His play calling duties were eventually stripped by Dan Snyder during the 2009 season and was fired following the season.
Who should be the offensive coordinator of the Chiefs in 2012?
However, Zorn has had some success as an assistant coach with the Detroit Lions, Seattle Seahawks and Baltimore Ravens. As an assistant, Zorn has reached postseason success with those teams. Zorn would make the most out of a second chance as the offensive coordinator. If he is given the job, he won't have to worry about handling two big duties like he did with Washington.
Another strong candidate outside of the system would be Hue Jackson, who was let go by the Oakland Raiders as the head coach last month.
As an assistant, Jackson has helped offenses get better over time. Jackson has spent time with the Redskins, Bengals, Falcons, Ravens and Raiders as an assistant from 2001-10 before being the head coach of the Raiders in 2011. If Jackson can't land a head coaching elsewhere, Romeo Crennel should make him part of his staff.
But hiring Jackson comes with a loss. According to Adam Teicher of the Kansas City Star, Zorn may resign if he is not given a promotion.
