Whether you love or hate Jim Harbaugh you have to admit the guy can hire strong assistant coaches. It makes a ton of sense why Saban loses basically his entire coaching staff every year. There isn't a program in the country that wouldn't want Alabama's high level of success over the last 10 years. So maybe one of the assistants can replicate it at your favorite University. Michigan has fished from that lake bringing in 2 offensive coordinators with the latest being Josh Gattis.
What is interesting to me, is that Michigan has had nowhere near the success Alabama has on the field and programs come after Jimmy's assistants every off season.
