Northwestern coach David Braun says Iowa’s offense has made progress this season, even though the way they play has not changed. The Wildcats take a 3-4 overall record into Kinnick Stadium on Saturday.

Braun says with running back Kaleb Johnson the Hawkeyes have a big play threat.

Braun says new offensive coordinator Tim Lester has put his stamp on the offense.

Under Braun the Wildcats have played well on special teams. He says that will be a challenge against the Hawkeyes.
