Not that the 4 corners schools wouldn't want an invite (especially with the writing on the wall from today). And he's right, doubling up on markets is a thing of the past. The only exception to that rule I can think of is USC and UCLA, but that's the #2 TV market, more than double the size of Phoenix and almost 5x the size of the SLC TV market.
I really expect the B12 to add only one of the AZ schools and certainly not UU.
