Absolutely. This is going to become a frontburner conversation for baseball especially as a new CBA comes onto the horizon and dominates conversation after the complications of the pandemic are addressed. It's important to note that you're talking about two significant different issues, though. The NFL has national broadcast deals. Fewer games, so they can do the national deal for all of them. Baseball, hockey, basketball -- they have the local rights holders because they have so many more games to broadcast. That's way different. Requires a vastly different infrastructure and price tag and, yes, delivery is part of it.
So the way for baseball to get on Disney+ with a game -- and that would be fantastic -- isn't to do it through a local deal, like Fox Sports Midwest, it's through the national deal, via ESPN. So, for you as a Cardinals fan, that might mean you get the Cubs-Nationals on Disney+ some Sunday night, but doesn't change how readily available Cardinals games are.
For the local rights holders, the ones that carry the bulk of the games in baseball (again, vastly different than the NFL), the streaming platform is going to be what changes access.
