So, sorta?
These big marquis ooc used to be the only way you could play any of these teams outside of a bowl game. Now USC, Oregon and UDub are in the conference, so you don't have to schedule any of them ooc in order to play them. Then if you run through the playoffs, you play up to four big marquis games in a month, to finish the season.
I'm not really sure that they are all that necessary anymore.
