I'd imagine it's to get markets in Australia and other countries who follow these teams in their home countries to have more incentive to watch the NBA
Try the 'My Teams' app by NBC sports. I have Hulu TV and downloaded the NBC Sports app and my teams app to my phone. I synced my logins and was able to watch all the preseason games thru the arena feed. But i am 15 miles or so from G1C.
That’s what happened to me but FYI you will not get NBA TV if you get NBA league pass. Those games will be blacked out. I don’t even have Spectrum anymore haven’t had it in a long time but I find it easier to stream to my devices I can watch on the go anywhere. For NBA TV games I just use Slingtv. Works great.
I hope you don't mind if, the next time my daughter wants to come visit, if I could contact you for directions to your short cut. It could be a huge time saver.
