Iowa basketball coach Fran McCaffery believes added depth will help the Hawkeyes improve on defense. More than a half dozen newcomers join a team that finished last in the Big Ten in defense by giving up nearly 79 and-a-half points per game.

McCaffery says added depth on the front line will help on the defensive end.

McCaffery expects the newcomers to contribute right away.

The Hawkeyes finished 19-15 this past season and missed out on the NCAA Tournament.
