Iowa hasn't had the players the last couple years, other than Linderbaum. Getting very little out of the 2018 and 2019 OL recruiting classes is the core reason why.
From Dochterman on 10/27/2022:
In a traditional year, the Hawkeyes would have perhaps a senior tackle and guard to lead the unit. But none of their starting five are fourth- or fifth-year players. In the 2018 and 2019 classes, Iowa signed seven offensive linemen out of high school. Of the three recruits in 2018, injuries forced Cody Ince to retire during the offseason, Jeff Jenkins quit after barely a year at the school and
Jack Plumb has become a rotational tackle this year. Of the seven, Plumb is the only one who has played, and he could pick up his first start of the season Saturday at right tackle.
In the 2019 class, injuries have crushed guard
Justin Britt, who is out for the season.
Tyler Endres has yet to crack the two-deep.
Noah Fenske and
Ezra Miller transferred to Colorado and Nebraska, respectively. Fenske is a second-team center while Miller has yet to play this year.
Ince, who had All-Big Ten potential, and Britt previously were listed as starters before injuries ruined their careers. Plumb also has nine career starts. They could have formed that foundation up front. Instead, the Hawkeyes have started four sophomores and a freshman the past two games. It has led to protection issues — 23 sacks allowed, ranking 111th — as well as perpetual running-game problems.
As the line goes, so goes the offense. And so go the Hawkeyes.
