Iowa would be mentally impaired to let Tyler Barnes leave for any reason Coaching change included. He does a outstanding job and Iowa is lucky to have Him and any incoming Coach would retain Him unless He Himself is mentally impaired. at any rate I would almost Guarantee the next Iowa HC is either Tim Lester or Seth Wallace to keep Program and roster continuity and culture . and Barnes will stay in His present role and Kirk will have plenty of time with Grandkids and Family close. Bringing in an outside Coach would be very risky and I see Iowa doing what Michigan did when pool boy left and promoting from within,
