at least in terms of TV revenue. Not to mention that because they only have 10 teams they split a big pie 10 ways and so each of those teams is making out far better than any of the pac 12 teams with its fledgling network with a small footprint and relatively weak ratings.
The Big 12 was smart not to expand, even if it did really hurt BYU.
But I do not think the Pac 12 is going anywhere.
