Well good thing you alone, on a hardcore baseball site, and your viewing preferences, are the guide for how to view this move. Meanwhile, the rest of us will try to look at it more broadly and the point is relatively simple:
1) People who are looking for bang for their buck and quality depth of content are not going to find this price point, for this content, attractive. Netflix, at the same price point, is finding people leave because it's too expensive. They offer more for the same price. That's relevant. So what does that do? Basically leave you with a subset of diehards.
2) Another service....which, by the way, also has sports....is MUCH cheaper and offers the culture's biggest attractions. At, again, a MUCH cheaper price point. Paramount and Peacock? Ditto. Just less cultural significance. HBO? Less content and no sports, but....again....cheaper.
So who does this appeal to? Well, casual people with any kind of budget are going to balk at that price. Even here, a devoted group of baseball diehards, you've got about half the people saying "Screw that". Is it going to appeal to your 60+ folks? Um, likely not. They're what keeps the lights on for Direct TV because then they don't have to navigate streaming and wi-fi. So what's left?
This will appeal to a subset of a subset of a subset. None of the examples above have that problem. Why? Because they bundle the subsets together and anything you don't want is just a bonus you get. And...I'll say it again....for a CHEAPER price. This will fail no matter how much you try to will it not to with specious reasoning.
