See @scane's post above. It's confusing, but if you get the SEC network from your cable or satellite provider, you can watch live or a replay of Sat/Sun games on your computer, Firestick, cast it to your flat screen, etc.
I am seeing SEC/ESPN Network+ for Sat/Sun games which requires a subscription other than your regular cable/satellite subscription w SEC Network or ACCN - can anyone confirm? That is how I am reading it.
