Because folks are forced to buy the entire bundle of channels for $70+ per month, including lots of expensive sports that only a fraction of viewers watch? That's not how it works with streaming though. You'll be able to buy, say, 20% of the available first-run TV content within any single major streaming service. And that will include a sprinkling of major sports, appealing to casual fans. But if you're a big fan of a particular sport/team, well, you'll need their dedicated app to watch the great majority of their regular season games (whether in-market or out-of-market). And those fans will have to cough up some serious cash to do that. (There will be a shakeout in sports economics a few years down the road that'll be fun to watch.)
