I don't know if it's been covered, but can you NFL on KODI? I'm looking at getting the Firebox. Did you have to set it up yourself or can you buy it already with what you want on it?
there are a few I have heard of people using.
grapevine is that you can use addons like Sportsdevil, Prosports, and Project D. Not that I would use these add-ons, but just saying.....
