generic stream (live games)
note: audio/video (A/V) is not consistent across all venues. Some sites have a tendency to have a hum, or a high pitched squeal (very annoying), or no audio, or chopping/pixelating video.
normally at arenafootball.com, if you hover mouse pointer on the scoreboard, you'll see 'Live Stats' which is a better experience when it works. There is a scoreboard, live stats and video streaming when there is a live game, except when there is a broadcast on NFL Network.
