Android TV Features:

Just in case anyone is wondering.
Only thing with NFL mobile is how far behind their streams are. I have their service for free threw Verizon and rarely use it because it's ~3 minutes behind on the game clock. But their notifications on their app right above the stream is on time...so you'll get a spoiler or two if you accidentally glance at. Stupid as shit
