We would be a much better fit in the Big 10. However, do we ever realistically expect to be a player in the football playoff? You don't need to be in a major conference in basketball to make noise. We'll find a place if it ever comes to that.
Big 10's a wash at best. We have as much in common with schools in Indiana, Michigan and Ohio as we do Texas, minus 20 years of playing each other. Iowa, Minnesota, and Nebraska are good fits but at the same level as KU and less so than KSU and OSU. Purdue is probably a pretty good fit.
I think the lack of Texas recruiting would hurt our football program more than the easier schedule would help it. I wouldn't mind the Big 10, but if we could guarantee a stable and lucrative Big 12 I'd take it every day of the week.
