This is true. I fear that with the switch to a new offensive line coach coupled with a lot of young tackles that Iowa will not have a good oline this year. If they can somehow pull it together by the next game, great. Otherwise Iowa will not be running the ball well the rest of the year.The difference between how this season has unfolded between these 2 teams was in the early schedule and offensive improvement. They faced 3 very good defenses with an offense that was struggling with a bad QB behind an offensive line that had yet to gel. Since then the offensive line has become completely dominant running the ball, like all Badger lines seem to do, and Mertz has become a game manager. Iowa's offense OTH has continued to struggle.
