(see B1G addition of awful Rutgers, etc) so i'd be FORWARD thinking and add perennial power BSU over CSU. are there more tv sets in Boise? nope. but i guarantee more people are interested, nationwide, in a BSU vs Oklahoma rematch than CSU and OU.

in addition, adding a team that is consistently top-25 will build conf SOS and allow your "champion" to have more claim on coveted CFP spot(s).
