Of parity in the ncaa basketball championships. When you see that power conferences are sometimes going ten deep in getting bids while smaller conferences are getting one every year it really isn't a format for parity. Yes we see examples like Gonzaga, however we are also dealing with the variate of schools that don't play football at all, but focus their resources on basketball.
This changes the dynamic of your argument.
Now an expanded playoff where everyone gets one team in with two wildcard spots (assuming Indy's get placed in conferences) would make ten conference champions and two wild cards. It wouldn't be perfect, but it would begin shifting recruiting almost immediately. The waiver wire would bloat and more kids could stay closer to home so their families could afford to see them play.
So many factors that would over time change the landscape.
