wgr app can't stream the game due to nfl rules. Not to mention your battery inside the stadium will go really quickly. your best bet is to get a portable radio, I used to use a Sony one from walmart that cost about 30 bucks and worked great. The cheaper ones didn't work well in my experience. However you have to tune in to WGR and the broadcast is about 5-10 seconds behind real time, so you see it happen and then the call a few seconds later.
