Iowa linebacker Nick Jackson says the Hawkeye defense feels it has something to prove this season. The former Virginia transfer was named third team All Big Ten in his first season with the Hawkeyes and was one of several players who decided to return for an additional year off a unit that finished fourth in points allowed.

Not only is the Iowa defense experienced it may be the oldest defense in the country.

Jackson on the keys to Iowa’s success on defense.

The Hawkeyes open August 31st at home against Illinois State.
