One thing I would say is that not all Premiership games are televised now. For example, the Irish vs Chiefs game is not even being streamed. BT might still be filming it (I guess they are), but saving the cost of broadcasting it.
I logged in to BT to watch rugby and no game is on right now, with the Falcons game delayed till this evening.
Rather than broadcast our game tomorrow, BT are leaving BTSport2 with no content until 6pm. I could be wrong, but BT look like they are stepping back a bit from Rugby Union, cutting costs.
