https://www.samsung.com/us/appstore/ lists all Samsung apps for their TV's. I didn't search for NBC Sports, but you can try.
If no luck, buy a Roku or stream from your phone or tablet.
Just bought a Samsung Smart TV and I can't find the NBC Sports App in the Apps menu - just returns nothing when I search for it. I didn't have this issue on my TCL Roku TV. Any thoughts? I don't see anywhere that says the app isn't available on Samsung's Smart TVs.
