Chuck Knox passed away on Sunday. He finished his coaching career with a record of 186-147-1, yet never made it to a Super Bowl. Who are the only other two coaches with at least 100 wins in the Super Bowl era, with even better career winning percentages, who also never made it to championship games? Both coached in the same division as Knox in multiple seasons.
Marty Schottenheimer (200-126-1) and Don Coryell (111-83-1). Schottenheimer became Kansas City’s head coach in 1989, competing against Knox (Seattle) in the AFC West through 1991. Coryell (San Diego) and Knox were both in the AFC West 1983-1986.
