Iowa defensive coordinator Phil Parker credits consistency with the Hawkeye’s continued success on defense. Parker is entering his 25th season on the Iowa staff and his 13th as defensive coordinator.

Iowa gave up only a little more than 13 points per game last season and that unit looks strong once again. Parker says it is based on sound fundamentals and limiting mistakes.

Parker says the Hawkeyes have played a similar style of defense for several years.

With a season under his belt Xavier Nwankpa could have a breakout season at safety. Nwankpa stepped into the lineup in a Music City Bowl victory over Kentucky after Kaevon Merriweather opted out and returned an interception for a touchdown.

Nwankpa says as a sophomore he is a much better player.

The Hawkeyes open at home on September second against Utah State.
