I think it's going to be a very big rude-awakening for the B1G--it's existing members and USC/UCLA--when the 10:30pm slots gets scheduled. when UM/tOSU visit USC or UCLA, they (and their fans) aren't going to be excited to be watching a 10:30pm game. Also, USC and UCLA are going to want some afternoon games, which will then take away from a B1G game during the day. How this will be juggled is going to be harder than I think all parties involved believe it's going to be (too many large egos involved).
The PSU game scheduled for Thanksgiving Weekend late on a Friday is already starting to show the angst that is about to boil.
So, getting UO/UW to come and still all 6 home games for them at 10:30 is not something they will just accept...
