One thing I've learned since the Big Ten Network came about is that they don't even broadcast all of their Big Ten football or basketball games. In fact, since BTN's arrival more games are on ESPN and ABC than they ever were at least here. What's the point of having a dedicated channel and it's overflows to a certain conference when you give the games to other networks? Oh that's right. Money.
Point of my story is, I would personally expect more PAC12 games to be on channels you can receive (ABC, CBS, ESPN etc..) outside of P12N in the future even if DirecTV gets the channels or not.
I'm not sure how the big 10 handles what games are ESPN etc. the Pac 12 split the games up evenly with Fox and ESPN/ABC. They have a draft to see who gets what games. So, one provider wouldn't get all the good games. 1/3 Fox, 1/3 ESPN and 1/3 Pac 12 Network. There will always be some good games shown on the Pac 12 Network.
