That sounds too much like making Iowa a surrogate team to root for instead of the Gophers. I have other teams that I have a special interest, such as Bemdji State. But root for a rival? During the Big Ten schedule, I have no reason to root for Iowa any more than for their opponents. Would Iowa fans be rooting for us if the roles were reversed? I don't root either for or against them. If I watch them, I just look for an interesting game, I tend to root for the underdog.
Now, during the Bowl season, I will generally root for Big Ten teams, unless their fans have been really insufferable.
