The HC job was supposed to be Greggs when Gibbs retired. It was a LOCK. Danny boy had a change of heart after talking to his players & interviewing Gregg FOUR times. Williams will NEVER be a HC in the NFL again. Mularkey, WAY down the road MAY get another shot, but a doubt it. The POINT is you said they have both gone on to success after leaving the Bills. Mularkey was DEMOTED from OC to position coach after leaving the Bills.................You call that Success??????? Williams had GOOD players in DC & didn't do much with them, he not only did not get the Head Coach job PROMISED him when hired by Danny Boy, but he even lost his DC job which paid a LOT of Money.....................You call that Success?????? I REPEAT Neither of those two will EVER be a HC again.
