I agree that we should add a guy like Sanders to the staff. Even if he can't coach (although I am sure these guys could offer some helpful pointers), I think they would relate much better to recruits, and really sell them on the developmental side of Iowa football. If Dallas Clark, Bob Sanders, Greenway, Dwight, etc. told me about how they went from 2 star recruits to making millions in the NFL because of the development they got at Iowa, I think it would resonate a lot more than someone who had never played at Iowa. The coaches would still have to be involved in the process, however.
I also think they would love the job more so than a young guy looking at it as a stepping stone, although there is nothing wrong with that.
