Err, I'd rather the game not be on NBA TV.
Why? It shouldn't affect local coverage of the game. Just makes it so those out of the Boston market can also see it.
I'm not local, have League Pass. NBA TV blocks League Pass games. Plus... I'd rather listen to local commentators than whomever NBA TV puts in place.
I am pretty sure for these games, NBA TV just picks up one of the local feeds, I don't think they send their own crew.
I could be wrong, but I think Fan Night just decides which of the league pass games gets moved to NBA TV.
