I appreciate your feedback! I'm starting to really lean that way too. Sure, a couple had down years, but they have a great track record over the years. A couple of these teams have been a "if they do well next year they're in," and without fail that's a down year. It might just be time to bite the bullet and do it. There are three 5* prestige teams (although after this year two could drop to 4*).
One thing to consider is all these teams are in different areas. Regardless of which team or teams, I would be adding 1-3 NEW television markets for the Big 12...which brings in money...which truly runs the show.
