Next year they are gonna add Arizona, Gonzaga, UConn on top of having Kansas, Houston. That will be a complete meat grinder of a conference in the coming years.
If the Big 10 was expanding Wash and Oregon weren't going to happen and they wouldn't have signed on to a long term GOR. They would have probably stayed in the PAC depending on how long the GOR was.
Gonzaga and UConn aren't done deals yet but apparently they are giving Yormark approval for it.
