Iowa has really relied on its defense and special teams through its first two games of the season. Just ask Defensive tackle Logan Lee.

71 snaps? That is a lot for the 6-foot-5, 275-pound lineman. But much of that is adieu to the Iowa offense being so poor. The Hawkeyes have scored 14 points in 2 games. Punter Tory Taylor has booted the ball 16 times. That is not a recipe for winning football.

The Hawkeye offense has to sustain some drives to give the defense a break. In particular, quarterback Spencer Petras has to be better. He has yet to throw a touchdown and has thrown for 201 yards.

Maybe that will come Saturday vs. Nevada. If not, this could snowball into a big problem when they move into the heart of B1G conference play. Iowa will need an offense for Michigan on Oct. 1 and Ohio State on Oct. 22.

The defense can only do so much, especially against potent offenses in the future.
