Are there any effective ways to watch NFL games (preferably live) on Android devices this coming season? Ideally, they'd be available in high resolution and streaming, but what options are available? I know there is a DirecTV app, but it seems to require having a DirecTV subscription, which many do not have.
The NFL keeps a tight rein on its broadcast rights. Further, the outfits that ponied up those huge payments for those rights are not going to be happy if there is a cheaper alternative. So, no, there is not going to be a way to watch live NFL games without subscribing to cable or satellite.
If you're okay with watching games after the fact and you have an Android tablet, there's Game Rewind.
Things may be different outside the U.S. Using a proxy to bypass such limitations skirts the edge of legitimacy (in my opinion).
