Iowa defensive lineman Yahya (why-yay) Black credits coaching consistency for Iowa’s success on defense. Phil Parker is entering his 13th season as defensive coordinator for a unit that finished fourth in the country in scoring defense during a 10-4 campaign.

The Hawkeyes have an experienced defensive line that includes former Southeast Valley star Aaron Graves. The junior had 37 tackles last season.

Graves says with experience comes a larger leadership role.

The Hawkeyes close spring drills with an open practice on April 20th.
