You couldn't be more wrong. Do you remember a school that use to be in the big 12 that dominates the college football market in denver? have you been to denver recently? do you know the distance between foco to denver? There are probably as many hawkeye fans in Denver than CSU. I don't know the statics but there are a TON of non-colorado natives and while living there if I asked someone where they were from less than 10% said colorado.
Again, this is not about fan support. If it was Rutgers wouldn't be in the Big 10.
CSU and ISU are very similar universities with similar enrollments. They have access to the Denver market, we have access to the Des Moines market. Outside of us being in a Power 5 conference, what advantages do we have over CSU?
