The blueprint is there in this changing landscape
They should do a live stream post-game show on Youtube. They can still get advertising dollars and sponsors and ad placement during the live stream. Put the show on in direct competition to whatever the NBA is doing for the Nationally televised games, and then when the time comes, license out the show to have a multi-stream just like McAfee did with ESPN.
TNT can scale it down some if they want, but now that they don't have to fork out billions in this NBA deal, they should have enough bread to keep the show together.
Other shows/podcasts are already doing this on a lower scale. Gil's Arena is an example of a platform doing this, so there is a pathway to do something different and keep them together.
They already have a huge social and online presence with Bleacher Report and House of Highlights. And those social media teams know how to market shyt. The NBA fan that follows those pages/platforms will know when Inside the NBA is on and can be linked directly to it everywhere.
