I mean, the 12 team set up with a CCG gets the extra CCG money because you get one extra nationally televised game. adding crap teams obviously isn't going to get that benefit because they dilute the pool during the year. the 12 to get to a CCG only adds cash if the teams added add equal to or almost equal to revenue that the average team in the conference already provides. They could get away with providing a good amount less if you assume the bigger draw schools are going to end up playing in the CCG anyway though I guess.
