Iowa football coach Kirk Ferentz has made additional changes to his coaching staff. Recruiting coordinator Eric Johnson will move from tight ends coach and assist with the defensive line and graduate assistant David Raih will coach the tight ends. Ferentz says the change will allow Johnson to focus more of his attention on recruiting. He says the demands of that segment of the organization are so strong that his goal was to get Johnson in a position where he could dedicate more time to that area. Ferentz says Johnson is doing  a lot of work for the Hawkeyes, with regard to personnel, and it’s a “critical job, and always has been”, especially in the way recruiting is constantly undergoing changes.  Ferentz says by assisting with the defensive line Johnson will be more free to travel during the season. It is the latest of several changes on the Iowa staff which includes new offensive and defensive coordinators.
