Among the first moves that Herm Edwards made on a Kansas City Chiefs coaching staff was to make no move at all at defensive coordinator. Edwards will retain incumbent defensive boss Gunther Cunningham, with whom he has some history, and whom Kansas City veterans urged their new head coach to keep. Kansas City ranked No. 25 in total defense in 2005, but the consensus around the NFL was that the revamped unit demonstrated progress. By keeping Cunningham, 59, Edwards is hoping that continuity will allow the defense to progress even further in 2006. The two coaches share many philosophies, although Cunningham might have to make alterations if the Chiefs are the employ the "cover two" scheme that Edwards has favored.
