If I had to guess, 3-5 years. The bigger problem for Iowa IMO is it sounds like once KF is done Phil Parker is done as well. So when change happens it could be massive.Thanks for the kind words about Rhule. I agree on the trash talk. How long do you think Ferentz keeps coaching? With three B10 West teams changing coaches, it's going to alter the division one way or another. Ferentz may need to adjust his formula.
