For now, I open up this app NextVR and put my phone into a virtual reality headset. The game has its own set of announcers, some dude from NYC and Antoine Walker. The main camera is set at center court so you pretty much follow the action left-to-right and have to move your head in the headset to follow the action. The score of the game is superimposed on the floor so you have to tilt your head down and look below the action to see the score. They sometimes switch to a baseline view, view is right behind the basket. It doesn't quite feel like sitting courtside but it definitely feels like you're closer to the action. That said, I think basketball is the best sport for VR because you can basically follow the action without having to change cameras a lot. Football has too much real estate/area to follow the game and hockey, the puck is too small to keep up with the action. I haven't watched baseball but I'd imagine the wide area would also make it difficult.
