OK, here goes.
Sinclair owns the former Fox Sports Net channels, now renamed Bally’s Sports.
Sinclair also owns the digital sub-channel Stadium, which is also available, for free, on services like Pluto or Stirr. IMHO, there is little content on Stadium, but it is, well, free.
The channels now labeled as “Stadium Sports Atlantic” and “Stadium Sports Pacific” are NEITHER Bally’s nor Stadium. They are mainly for cable. Because of cable’s very limited capacity, cable only carry the local RSN(s), while DirecTV can carry all of them. Meaning DirecTV customers can get the sports pack of out-of-market RSNs with the live sports, while those still with cable cannot. So Fox launched the Fox College Sports channels for cable as a sort of poor man’s sports pack, with games gleaned from the various RSNs.
All well and good. But VERY RARELY there is an original game on one of these channels. DirecTV carries a part-time version of FCS, when there are original games not found on any RSN.
All that has happened is that Sinclair has renamed this service from “Fox” to “Stadium”.
Access to it is via the sports pack, as always.
