"I learned a lot from Al Davis. I think I kind of became the coach I became in the league, demanding and detail-oriented, because of what I learned all that from Al."
Cunnnigham, one of the NFL's most revered assistant coaches, got his first NFL job from Al Davis. He was the Oakland Raiders defensive coordinator from 1992-1993, before beginning a tumultuous 11-year run with the Chiefs.
In his time in Kansas City, Cunningham often faced off against his former mentor, first as a defensive coordinator for one of the best defenses of the mid-90's then in a two-year stint as a head coach after Marty Schottenheimer's retirement. Cunningham was replaced by Dick Vermeil, but he returned to Kansas City as a defensive coordinator from 2004-2008 before taking his current job with the Detroit Lions.
