I don’t know if I agree with this at all. Iowa went 37 for 112 yards last year and 36 for 105 the year before that.
I’d argue that ISU’s DL will be better than either of those years and Iowa’s OL won’t be quite as strong as those years.
I also don’t think the Iowa front will be some juggernaut against the run, but tough to argue against as ISU’s OL will definitely a question mark for run blocking.
Iowa was down at least one offensive lineman vs ISU in Jackson, and I think a second in Banwart. Also Goodson didn’t play as much.
