How tf do I watch the kings in Sacramento on my TV……??

I have the NBA app “can’t watch local game” I have Fubo “local game” can’t watch

So how do I get CBS Sports Sacramento? If the only thing I have at home is WiFi …… do I have to add a tv package from Xfinity just for 1 channel?? Do I have to get Direct Tv??? So dumb

I do use Stream 3ast but I hate the buffering it does sometimes….
