Free streaming audio of NFL football games?

The NFL now prohibits radio stations from streaming games online. You may still be able to catch a station doing it, but it's generally a dead end. So where can you catch a game?

The NFL offers their own paid streaming package: Field Pass. $29.95 for the whole season, $9.95 a month, or $14.95 for just the playoffs and SuperBowl.

Sirius satellite also offers NFL radio as part of their programming. You can listen online as well as through the normal receiver. There is a free trial available and even an iPhone app.

Sprint offers subscribers their NFL Mobile Live, which includes at least some audio and video. Text NFL to 7777.

Those are the only official and copyright-respecting ways to listen to NFL games online. There are, of course, places like Justin.tv where users often stream games.
