don't know if Ole Miss will be interested, but if they do something to entice two others to break up a game then OSU and WSU could each schedule one or one of OSU and WSU could schedule 2.
Like break up BYU-ECU and then OSU plays both of them. But problem with that specific example is BYU-ECU is in September.
It just makes it more difficult to pull those types of things off for later season games. But of course they need to move quick before the conference game dates get announced for various conferences.
