I watched some examples with the PSVR (PlayStation 4 VR) headset. It isn't that good. I never felt like I was sitting in the courtside, but probably because the quality of the video isn't that good. Also, it is very umcorfortable to keep moving your head to follow the plays. In real life you only move your eyes, not your head.

I watched an NBA game on the NextVR app and it was amazing. "Courtside" view is pretty useless, but the default view predominantly used the basket stanchion cameras, switching from end to end whenever the ball crossed half court.

Getting a three-dimensional sense of the game was amazing. Looking around and seeing and hearing things you don't see and hear on TV was also great. FOV is still the main limiting factor, but mostly, the behind-the-basket camera angle lets you look around and get a much better sense of what's actually happening on the court--with the downside of actually having to look around.

I did this on the Gear VR (which actually has better resolution than the original Rift), and it was amazing. The streams would die once in a while, but it was SO fun to watch. You could switch around to different views while you were watching, too. Timeouts made me feel like I was there when they didn't cut to commercials. :)
