Some details have leaked about Oregon State and Washington State's plans for a football schedule next season. They will formally be in the Pac-whatever conference, but will almost be quasi-independent.
6 of their games will apparently come from the Mountain West, with three at home and three on the road. The MWC would go from an 8-game conference schedule to 7+1, where each team would play 7 conference games plus one against either OSU or WSU. For their trouble, the Pac-2 will pay the MWC $14M.
OSU/WSU would not be eligible for the MWC title, and thus not eligible to claim one of the conference champion auto-bids to the CFP, as the CFP set the bar for eligible champions to come from a conference with a minimum of 8 teams. So the only way either could make the expanded CFP is as an at-large (good luck).
Both teams already have previously scheduled OOC games against other power conference/FCS teams, but some of those were MWC teams, so they will likely need more games. Washington State does now have its Apple Cup game with Washington scheduled, and Oregon/Oregon State are apparently working on trying to do the same, but they have more obstacles to overcome than the WA schools.
Also, both schools will likely play each other twice, home-and-home. So with all that said, each will probably still need to pick up two more games from somewhere to get to 12.
