"Between changing their head coach and then their quarterback late in the year, the Chiefs experienced so much drama that this little fact slipped through almost unnoticed: By season's end, the Chiefs had one of the NFL's best defensive teams.

Opponents over the last six games struggled to move the ball and score points against the Chiefs.

It wasn't lost on Romeo Crennel. He said recently that things worked so well at the end of the season that he would in effect continue to serve as the defensive coordinator even though he's now the head coach.

Crennel also indicated he intends to retain the rest of the defensive coaching staff."
