The Kansas City Chiefs have fired head coach Herm Edwards, bringing to an end a three-year tenure marked by the team getting progressively worse, and ending with a disastrous 2-14 campaign in 2008.
New general manager Scott Pioli was hired 10 days ago, and it has been widely assumed in NFL circles that he was planning on firing Edwards. This afternoon ESPN reported that the firing was handed down, and Pioli will be searching for a new head coach.
The question now is whether Pioli will focus on an up-and-coming assistant (like Arizona Cardinals offensive coordinator Todd Haley) or try to make a big splash with a proven coach (former Broncos coach Mike Shanahan and former Steelers coach Bill Cowher have both been mentioned).
Edwards went 15-34 in three seasons as the Chiefs' head coach. Edwards previously spent five seasons as the head coach of the Jets, compiling a 41-44 record.
