I just set this up today and it worked great. I am a Steelers fan, but I live in Bengals country. That means I don't get to see many Steelers games, because they aren't broadcasts locally on TV.
So I used a GPS spoofing app:
And a Chromecast dongle hooked to my TV:
And the NFL Mobile app:
Enable "Mock Locations" in Developer Options.
Open Fake GPS app and enable a location where you know your game is broadcasting.
Open NFL mobile app and voila!! You now have access to the local games being broadcast on FOX and CBS for wherever you set your fake GPS location to.
You also need to enable "Screen Cast" in the Chromecast app, so you can mirror your phone screen to the TV. Set your screen timeout as high as you can.
I'm sure someone has already done this, but this was my first time, and it worked like a charm.
You may have to kill the NFL app to get it to switch locations as you change your fake GPS location. I always set my location first, then make sure my NFL mobile app is completely killed. Then just restart the NFL app. The new games should populate in the watch now section.
Hope this comes in handy to someone!
