Iowa has been one of the hottest teams in the country halfway through the college football season.

The Hawkeyes are sitting at No. 2 in the country, undefeated at 6-0 and 3-0 in B1G play.

College GameDay analyst David Pollack isn’t sold on the Hawkeyes. To be fair, he does not trust anyone in the top 4 and believes all of the teams have deficiencies.

Pollack on the McElroy and Cubelic In The Morning radio show spoke about how before Penn State QB Sean Clifford got injured, he played well against the Iowa defense.

“Let’s put into context what Iowa was this weekend before Sean Clifford got hurt, said Pollack. “It was 17-3, he had almost 180 yards of offense by himself through a quarter and was absolutely carving up the secondary of Iowa because of their lack of speed, their lack of pass-rush.”

He believes there are holes in the Iowa defense that teams will be able to exploit.

“I think you can expose that zone defense in the back end when you have time and you space them out,” said Pollack. “I think (Penn State) was absolutely destroying them. I think Penn State would’ve walked away with that game (if Clifford was healthy).”
