Spring drills are underway at Iowa as the Hawkeyes look to fix an offense that ranked next to last in the Big Ten despite a 10-4 finish to the season. That includes a passing game that had a completion rate of well under 60 percent.

That’s Iowa coach Kirk Ferentz. The Hawks must replace All-American center Tyler Linderbaum but Ferentz feels an offensive line plagued by inexperience last season will show marked improvement.

Ferentz feels the offensive line made strides late in the season.

Ferentz says depth on the defensive line has allowed Logan Jones to move to center to become one of the candidates to replace Linderbaum.

Spencer Petras and Alex Padilla are on-two on the depth chart at quarterback. Joe Labas is listed third.
