Not surprising, With the Suns and Diamondbacks gone it wasn’t worth it for Diamond to run an Arizona RSN with only the Coyotes.
Watching this whole saga unfold, it seems you really need a MLB team for a RSN to survive - which makes sense, since you have up to 200 days of games covered, if you count Spring Training. San Diego is probably more of an exception than the rule, since they were the
only team in town, and getting paid an exorbitant amount because of it. The San Diego colleges don't have enough interest to add filler program over the winter, since USD is a smaller school and SDSU is covered by the Mountain West's agreements.
I watch all of this with curious interest, to see what the Pirates do - if the partner with the Penguins/FSG on SportsNet Pittsburgh, or if they take the "easy" road, and the 80% rates from MLB.
