At least 2 of the 4 of Washington, Oregon, Standford and Cal will find their way to the B1G eventually. Maybe all 4. Washington checks off all the boxes for what the B1G would want athletically and academically. The other 3 have at least one con. Oregon has the best brand of the 4 and I believe the 7th largest fan base in the nation. USC and UCLA will need at least 2 travel partners. All the reasons the B1G would want at least 2 more western teams have been posted multiple times, so I won't hash them all out again. Here is one reason I think at least 2 more western teams will join the B1G that hasn't been talked about as much......
If the B1G and SEC continue expanding to 20-24 teams, it isn't realistic to think that a 48 team Power 2 will only include 2 teams west of Lincoln, Norman and Austin.
