We have seen with Rutgers and Maryland, you don't have to have dominating programs to be included. You have to be in a large population area. I would say the teams being mentioned fall into that category.
That was add a time when it was all about making money off the amount of cable subscriptions in the area (NY, MD). The financials are now moving towards brand/viewership.
Does UO/UW bring enough eyeballs for FOX to want to keep all current B1G teams whole if they're added? Maybe. Have to see what FOX does if the PAC12 implodes.
Stanford/Cal, as some have mentioned, is a hard No.
