The direct answer is yes, you absolutely need one NBA League Pass VPN. Unless you wait 3 days to watch the local market and national televised games.
Unfortunately, this is the current state of affairs due to the NBA’s TV deals prohibiting streaming of local games. In addition, games are broadcast ESPN, TNT, ABC, and NBA TV are also not available live on League Pass.
Well, that’s an inconvenience to say the least. This is exactly why you need a VPN. You can bypass these blackouts by hiding your real IP address and providing a non-governmental or international IP address instead. You can watch every game live as long as you are connected to the VPN.
