I don't know anything, but I love UCLA and USC joining the B1G.
I feel that ND is out, mostly because ACC is an easier path for them in a conference.
I have to guess that will go to 20, and cover the map for logistics and geographics from coast to coast. I can see the Big Ten changing it's name to B1G officially, and adding Arizona, Colorado and perhaps Utah (or Stanford) to link them to the Central/Midwest, but also adding Virginia to the East. All new members would be AAU with the lone exception Huskers.
B1G would look like this:
West Side
UCLA, USC, Arizona, Utah, Colorado
Central
Nebraska, Iowa, Minnesota, Wisconsin, Illinois
Midwest
Michigan, Michigan State, Indiana, Purdue, NW
East Side
Ohio State, Penn State, Rutgers, Maryland, Virginia
This would be a conference that can represent football, basketball, baseball, and women's sports as well.
2 Divisions - West Central and Mid East - with divisional conf game, with the winners playing for conf championship.
From East Coast to West Coast, there will always be a B1G game on (football).
It could even go by adding one to each regional pod, like - Stanford, Kansas, ND, North Carolina.
I am not smart enough to figure out the scheduling, but we would be B1G and cover the map and markets.
That's a B1G guess for sure lol. But who knows, everything is hearsay or a guess until it's official.
