I really like to think somebody will cause some movement, because it is going to take something like that for BYU to even have a chance at joining a P5 conference.
But the B12, as much as anybody, would seem to have incentives to expand its conference to maximize TV money. It doesn't work for them (or so were told). I know there are important structural differences - mostly how the conference handles tier-3 rights - that make the calculus for B1G different than for B12. The short version is B1G gets conference-wide value for TV inventory by using the B1g Network. B12 does not get that kind of value, because individual teams control tier-3 inventory, and there is no conference-network, anyway.
So, with all that in mind, is there a clear explanation for how adding teams to the B1G increases revenue on a per-team basis?
