Kansas City Chiefs interim coach Romeo Crennel celebrates with his team at the end of an NFL football game against the Green Bay Packers on Sunday, Dec. 18, 2011, in Kansas City, Mo. The Chiefs won 19-14, giving the Packers their first loss of the season.

KANSAS CITY, Mo. — Chiefs offensive coordinator Bill Muir has given his unsolicited endorsement for Romeo Crennel to be hired as Kansas City's permanent coach.

Muir said that the defense has "turned the corner" and that "it would be a shame to change that."

Crennel was elevated to interim coach nearly two weeks ago, when the Chiefs fired Todd Haley after a 5-8 start. Crennel provided a calming influence last week, and Kansas City managed a 19-14 victory over the previously unbeaten Green Bay Packers.

Muir is just the latest to endorse Crennel as the full-time coach. Star linebacker Tamba Hali said he'd like to see Crennel stay next season.
