I also like how you leave out other crappy teams like Illinois and Indiana......The Big Ten has many more opportunities at easy wins in the football schedule than Big 12 teams do.
It's not that your point doesn't have any merit, but you're being a bit extreme about it. Indiana is probably close to as quality a team as ISU, but their brutal schedule has not allowed them to get to the next level. Illinois probably has more raw talent than ISU, but is extremely poorly coached. Iowa and Iowa St usually have similar strengths of schedule. Last season Iowa St's was marginally tougher (although some metrics had Iowa's tougher, especially after the bowls), this year Iowa's will be significantly tougher.
I wish the Big 12 had a few more Kansas like teams.
Looks like your wish has been granted. Seems you have 4-5 "Kansases" in the Big 12 this season.
