I would imagine any of these things are possible and doable. I don't think the leagues want it though. I think the leagues will push for a unified platform. Why? It's simple. Small market vs. Big Market. The NFL is a different animal, simply because all games are broadcast over the major networks or streaming platform. The other sports though, market matters a lot. Do the Royals want to be competing against the Yankees in places in their territory? Nope. The costs of managing your own infrastructure are huge and while the Yankees and Mets and Dodgers can afford it, can the Royals and Pirates and Rockies? So the leagues will want these resources pooled and then sold through something like MLB AB / Extra Innings or via ESPN or NBA League pass. This way costs are shared equally as are profits. A Yankees stream is worth far more than a Pirates one.Now for sports will teams try some antitrust cases to get?
Not be forced to sell there local team packaged with ESPN / others?
The right to sell there local feed to anyone anywhere? / The right for the one team out of market package to not need you to buy the local teams rsn feed?
