Iowa State's a decent team and could certainly beat this Texas squad.
I agree that Texas fans are entitled, but losing to Iowa State and Kansas is never going to be okay at Texas, any more than Alabama fans would accept losing to Vanderbilt or Ohio State fans would accept losing to Northwestern.
Iowa State, Kansas, those are the teams that Texas MUST beat if Texas is ever going to get back to being a good program. A loss to Iowa State this year would be a pretty strong indicator that nothing has changed and we're in for another 5-7 type season, and that's something that Texas fans won't accept, nor should they.
