Yes, divisions may end up being the preference and the scheduling model could be determined by schools #15 and #16, depending on who those may be.
Some of the reasons pods may be preferable:
More central time zone kickoffs for West coast teams. Getting the West coast teams earlier kickoffs one way or another seems to be an important part of maximizing their value, same for any team really, they need good kickoff times. Pods allows the west coast teams to play 4 central teams a year as opposed to 2 w/divisions. That has the West coast teams playing 2 games in central times zones every year as opposed to just once a year in divisions.
Pods allow every team to play each other every other year as opposed to once every 4 years.
Minimized travel/optimal travel. Difference schools may have differing opinions here, but generally speaking each team would travel to each pod location once a year. Which seems optimal. UT for example would still have a large portion of the conference schedule in Texas, then also travel to the Southwest(LA/Phoenix) and Northwest(S.F./Seattle/Portland) once a year, as well as Kansahoma(perhaps every other year w/RRR).
Maximize championship game matchups. Allows for potential conference championship games between UT and OU or Oregon USC, while also providing the conference some flexibility in maximizing the matchup.
TLDR: For UT pods would mean playing K-State, Kansas, Ok St less and the west coast schools more.
Perhaps a north and a south division?
