Nice job, JDG, but though it's "ancient history" your list ignores the most successful coach in Bills history, and a hall of famer, who was a complete failure in his first head coaching gig in Kansas City - Marv Levy. The Bills were a laughing stock then for selecting an obvious failure as their head coach. I am not suggesting that DJ will achieve the same results - the situations are different in many ways - but any list of recycled coaches who achieve success the second time around certainly should have Levy at its head.
