Well, they had a game with Idaho they pushed back on the schedule for 2028. That contract was executed in 2022 before anyone was looking to leave the PAC 12, but they are paying the Vandals $675,000 for it.
There is nothing I find yet on the Griz/OSU, but the schedule was just posted, so I will keep an eye out to see if they list the terms of the contract for the 2026 game for the Griz.
Also found it interesting that the one team that still has an open date is Cal Poly and the only team with Suck State on their calendar is Southern Utah.
