You get audio coverage on iFollow but not video (at least, that's what Chesterfield and Barnet have this season). Don't know how many live games are shown on BT Sport, but we would presumably feature more regularly on those than we ever would on Sky.
I will really miss the video coverage on iFollow, even though this season has been an unmitigated disaster. Love listening to Charlie Slater and Mark Stallard and their genuinely entertaining commentaries, no matter how dire the performance.
