No, you would have to play them (location wise) just as ISU did. Which means you get OU at home, OSU there, Texas in Austin. Otherwise how does the hypnotical even make sense if you get to chose to have Texas at home to try "help" your argument? And correct, if iowa played Texas, TCU and WVU, I think they come out 1-2. TCU and Iowa are similar this year
Regardless, you're absolutely delusional to think the spread would only be 3-4. As
@Statefan10 already mentioned, we are not just "slightly" better than iowa. Iowa is not good this year.
