I was bored and went through the coaching staffs for each of the remaining playoff teams. Listed below are the coaches who seemed like possibilities to me (but I'm an idiot). They all have some college coaching experience and in the case of one an extensive HS coaching background. A couple of entries have pretty light resumes but have long NFL careers.

Green Bay Packers: Jerry Montgomery DL coach -11 years in college at OU, Michigan, Wyoming. Last 9 years in NFL
