There are only 2 places that I know of to watch games live, legally, without a login or subscription

1. NBC Sports, for Notre Dame games
2. BYUTV, for games being show live on BYUTV (ie Savannah State, various BBall games etc)

Those are the only two I'm aware of. If anyone knows of anymore, feel free to add. Let's just get this all out in the open for all CB to see.

As far as online/app that require a login

WatchESPN - Entire ESPN family of networks, including Longhorn and SEC, and some ABC games that are also on ESPN3
Fox Sports Go - Games on Fox, Fox Sports 1 and 2
Pac 12 Network
Big 10 Network
NBC Sports Network

To the best of my knowledge, CBS Sports has no online viewing at all, for CBS games or CBS Sports Network Games
