Teams like Missouri and OK state will leapfrog the other ones if they go undefeated. OK State will have beaten OU, Texas, Nebraska, and the winner of the Big 12 north (either Missouri or Nebraska again, most likely.) Missouri will have beaten OU, Nebraska, and the Big 12 south winner. I think both of those schedules should be enough to lift them past the BSUs, TCUs, and Utahs of the world. MSU will also have some serious scalps, with Wisconsin and Iowa (and, to a lesser degree, Michigan.)
