Iowa OL coach George Barnett had some positive things to say entering Week 5.

Iowa has looked better on offense over the last two games. A pair of 27-point efforts and 698 total yards of offense have the Hawkeyes feeling optimistic. Barnett would tend to agree.

To be fair, Iowa’s offense was dreadful against South Dakota State and rival Iowa State. The Hawkeyes totaled 14 points in both games and Tory Taylor seemingly never left the field. Anything better lately should be considered a victory.

But Michigan coming up is a bigger task than Nevada or Rutgers. The Wolverines have been explosive on the ground behind running back Blake Corum. The junior ran for 243 on 30 attempts and 2 touchdowns against Maryland.

Iowa will need to keep up with Michigan’s attack. Quarterback Spencer Petras has thrown for just 1 touchdown to 2 interceptions. In addition, he has yet to eclipse more than 175 passing yards in a single game.

Petras needs to be better to pull the upset on Saturday. That should start upfront against the Wolverines’ defense.

Maybe Barnett is looking to instill some confidence in this group. We should have a better idea where they stand after facing the No. 4 Wolverines.
