San Antonio to Pullman is 1946 miles, San Antonio to Storrs Connecticut is 1704.
The Texas schools, including Rice, have Tulsa and Tulane which are pretty close. But they still have a lot of Travel. More teams too. Connecticut to Tampa is a lot.
Also if UNLV joined, it would help them too.
But even so. If the PAC can get 10+ after CFP bonuses that would offset the costs. I would guess these newer schools are currently getting 6-7 mill per year, maybe more. The AAC lost their 4 best schools and markets, the legacy teams kept their 9, the new schools were no where near the departing schools' values. So something had to give.
