the other conferences know this and don't want the Big12 to have an even greater advantage by gaining $$$ from a CCG without expansion. The smaller schools, Iowa State - Kansas, aren't in favor of a CCG at 10 teams as well, which is why the Big12 never asked for one to begin with. (Or so they say, they're not going to ask for one if they think they'll be denied, but may have to ask for one now, so they can use that as an excuse to expand)
