OK, sounds great, but how would the money work?That's a very good question, one that's impossible to answer just yet.
In theory, a Mountain West with more good programs and more high-interest matchups commands a better media rights deal than what it is currently working with, but the league would have to figure out what percentage to distribute to each tier. It would also have to decide on things like "parachute payments" -- a Premier League system in which relegated teams receive a percentage of top-tier money (diminishing each year) to assure that the financial impact of falling off the ladder isn't quite as much of a shock.
There's also the issue of a school trying to draw up an athletic budget flexible enough to account for the sudden loss of a few million dollars it was planning on having. Obviously soccer clubs do this annually -- sometimes they do this very poorly and end up with serious issues -- and everyone would adapt, but there would be quite a bit of short-term awkwardness.
