Thought the issue was that if the game was being shown in the international area TV wise it won't be on Ifollow. Makes sense as the EFL won't want to compromise the monies received from the worldwide broadcasters. Clearly if a game is picked by Sky in the UK then it is more likely to be shown by international TV as well. Presumably however if you are in NZ for example and your local station chooses not to show the game the system will be clever enough not to block the stream for those in that area. But it won't just be Sky games there is usually a Saturday 3pm game chosen for the international feed so be a few of those over the season as well.
Presumably for home games the "commentary" will be the audio feed for the UK customers. Away games might just tap into the home teams commentary.
