SEC teams do not want to give up a home date by scheduling home-and-home, so they would rather over pay a Gumball State than lose the home revenue by playing elsewhere. Therefore, it is highly unlikely you’ll see SEC teams travel much. There is also the time zone issue and late return home which is also why Big Ten teams have been expressing their reluctance to add any more members outside USC/UCLA.
As the schedule stands right now, the August 31 game at Utah will be the first true road game outside Florida in nonconference play for UF since the Gators traveled to play Syracuse in the Carrier Dome on Sept. 1, 1991. They did play Michigan in Dallas at the beginning of 2017.
With the uncertainty about media revenue, most current Pac12 schools will not be able to pay large guarantees to attract opponents for the foreseeable future. Thus, a steady diet of Mountain West and Big Sky. Even those two conferences will become less available to the Pac12 as other conferences escalate their "buy games" values.
