New gig: Romeo Crennel is Kansas City’s interim coach for the final three games of the season. He replaces Todd Haley, who was fired in his third season of a four-year contract. The Chiefs are 5-8.
Previous job: Crennel was in his second season as the Chiefs’ defensive coordinator.
Age: 64. (He is the second-oldest head coach in the NFL behind Giants coach Tom Coughlin, who is 65.)
Coaching history: Crennel was the head coach of the Cleveland Browns from 2005 to '08. He was the defensive coordinator in New England during its dynasty days early last decade.
Playing history: He was an offensive and defensive lineman at Western Kentucky.
Known for: A hard worker who is a quiet professional and for whom players enjoy working.
Chances of becoming permanent head coach: He’ll be considered. The Chiefs’ defense has played hard for Crennel. He has strong ties to Kansas City general manager Scott Pioli. I think the Chiefs would love to see Crennel stay as defensive coordinator if he doesn’t get the full-time gig.
