The fact is that the Big 12 is a one team league - period! I get so sick of all the talk about the Big 10 being inferior. The Big 12 is absolutely overrated. Texas is a good team, but they are dominating that league. That conference is not even close to the Big 10.
The top 5 Big 10 teams would win the North. Also, the top 5 teams in the Big 10 would finish no worse than 2nd in the South.
