I’d say start with picking a team and go from there. You don’t really need to watch old games and such; it’s not like a tv show haha, no need to catch up on previous seasons. But YouTube has everything to get you started!

I’d look up fun content like Kobe’s old Detail show or breakdowns like that if you’re interested in the actual game. 30 for 30 documentaries can really highlight some great history like you mentioned.

And of course, get yourself a ball and go out to hit some shots. Even just on your own. Nothing better than the personal connection to the game to appreciate what these guys are doing
