Actually, it doesn't help Iowa's SOS, in fact, it really hurts Iowa there.
While it's more fun for the fan base that ISU is a door mat, they still typically play their best game of the year against Iowa. When ISU wins and are dog meat, ala just year, it makes Iowa look really bad.
yes, we will see by how many reply. i did edit that part as i knew it would come off snarky. i can only speak for myself but i don't really don't care about ISU much after the day after the game.
ISU is generally a laughingstock in college football and really wish we didn't have to play them year in year out.
