Iowa linebacker coach Seth Wallace has used spring drills to build depth. The starting trio of Jack Campbell, Jestin Jacobs and Seth Benson have combined to appear in 86 games and Wallace says additional practice reps were not needed.

Wallace says it was more important to get experience from the players behind the three starters.

Wallace says it is crucial to get the backups as much experience as possible.

The Hawkeyes close spring drills with an open practice on Saturday.
