Iowa has a much better defense than Nebraska, and a considerably less productive offense than Nebraska. In the wash, kind of the same.
EXCEPT that Iowa gains points and field position advantage from its special teams. Iowa is number one in the B1G in kick-off returns and punt returns, having a TD in each category already. Those yards don't show up in Iowa's offensive numbers, but they are every bit as meaningful and can be game changing. I have given up on the Gophers, under PJ, effectively using return teams to leverage field position and possibly score points. Because he likes to avoid mistake situations, I think he just doesn't believe in putting in the hard, continuous effort and practice on the offensive phase of the STs game. But, the Gophers really help themselves if they defense Iowa's return teams well. Don't let Iowa add to its offensive yardage via kickoff and punt returns.
