And the (semi-paywalled) SBJ reports that the WBD part of the issue is heading for a resolution. WBD is the AT&T Sportsnet. Despite the threats of just filing Chapter 7 and walking away on the come and gone March 31 deadline, SBJ believes that AT&T Sportsnet will continue to operate, and pay its rights fees, for this baseball season.
Pittsburgh (MLB Pirates, NHL Penguins) where the Penguins are owned by the same guy who owns the Red Sox and NESN, will launch its own channel using NESN filler material and resources. PESN (Pittsburgh Entertainment and Sports Network) is the working title, or just NESN Pittsburgh (with NESN standing for nothing in this case). Pirates are going to go along with the deal.
Rocky Mountain (MLB Colorado Rockies, NBA Utah Jazz, NHL Las Vegas Knights, with a complex web of different feeds based the different territories of each) is complicated by that very multi-city fact. No idea, but the Rockies might just sign with Altitude, which has the indoor Denver teams already. Denver doesn't need two RSNs. The Knights might make a deal with ROOT, which already carries its games in Montana, for a sub feed channel or just go OTA and wait for MLB or the NBA to come to town. Or make a deal with the Jazz for a Nevada/Utah based channel. OTA is an option for the Knights because Nevada and the rest of its claimed territory (other than SLC) outside the Las Vegas DMA is basically empty.
Houston, has contracts with DirecTV and Comcast that last into the next decade, will be sold off to some combination of the Astros and Rockets and continue to operate under a new name. It remains profitable.
Seattle, where they use the old ROOT Sports name, is only 30% owned by WBD. The Mariners own the rest, and it remains profitable. WBD will continue to own its share.
