(AP) -- One of the hallmarks of the Iowa program under coach Kirk Ferentz has been the continuity of his staff.

Not this season.

For the first time since Ferentz took over before the 1999 season, the Hawkeyes enter spring ball with two new coordinators; Phil Parker on defense and Greg Davis on offense.

After back-to-back 4-4 finishes in the Big Ten, Ferentz says it was time to shake things up. Ferentz says the staff changes allowed the program to re-examine what it's doing on both sides of the ball.

Iowa's spring practice runs through April 14, when they host their annual open scrimmage in Kinnick Stadium.
