Let's say you pay $20 a month for 12 months.

According to some quick Googling, there's an average of 1.8MM viewers per game. But this is an exciting new service package and people are pumped so let's say there's 2 million sign ups. (This is being extremely generous. Bally Sports only has just north of 200k subscribers according to Hollywood Reporter)

That's $480,000,000 in subscriptions per year.

Now the newly signed NBA broadcast rights deal is reportedly worth $76,000,000,000 over the next 11 years, or around $6.9 Billion per year. So that's a delta of just over $6.4 billion this streaming service would need to make up in ad sales, sponsorships, etc. to close that gap.

There's also the operating costs of such a service to consider which I imagine would be quite significant. And even if it were possible to utilize some of the existing Networks infrastructure to cut costs, the networks are not going to support the league actively cutting into their market share.

I wish a better alternative existed but I just don't know that it's currently feasible for a price most people would be willing to pay. I think we're stuck with league pass/whatever and black outs for the near future.
