Iowa coach Kirk Ferentz says the Hawkeyes are working on trying to fix problems in the offensive line.

Ferentz says they are still searching for the best combinations up front, especially at guard.

As far as the defense, Ferentz says while it’s playing well he would like to see that unit generate more turnovers.

Purdue next stands in the way, 11 Saturday morning at Kinnick, with the 9:00 pre-game on 1230 KFJB.
