"IF" Butch were to be hired. First assistant I would want on staff is Don Soldinger. Fight me if you want about that. But Don would be a home run on the assistant coaching end. Would get all these backs nfl ready and special teams top notch.
I love Don, he was one of my favorite coaches back in the day and toughened those kids up to make them great, but the RB coach needs to be a heavy recruiter because the position itself is not the most difficult to coach when compared to OL, QB, CB, etc. For that reason, i would stick with Ice if he would remained on staff.
