Fangio seems tailor-made for Green Bay. Austin would be great but might be headed for a HC job. Bettcher and Guenther would be good choices. Marvin Lewis would be solid. Bretsky might get mad at me if I bring up Jim Leonhard.
Marvin Lewis has been away from D coordinating for a long time. I would be VERY wary of him. Tons of experience but dated. I think that is part of the problem the Pack currently face.
Bud Adams told me the franchise he admired the most was the Kansas City Chiefs. Then he asked for more hookers and blow.
