For the NBA, I'm really hoping the rights for local go back to the league. While their league pass isn't amazing it would be so much better/smoother than Bally's (which I refuse to pay for).
Streaming is going to be interesting, as I think you'll start to see some sports (like soccer with MLS and NWSL with the whole league streaming) eat into the big ones who feel they can demand huge fees for a crappy product.
