Guys, Those sites are loaded with ads. I used them last year. The games are watchable, but I found that the links would routinely go down. This year I am using stream torrent. The link to d/l the product is :
http://www.softpedia.com/get/Internet/File-Sharing/Stream-Torrent.shtml.
After you have that software piece installed successfully on your pc and the icon on your desktop... open it up.
Then use this site :
http://www.myp2p.eu/competition.php?competitionid=&part=sports&discipline=americanfootball to find "streamtorrents" of your preferred game.
You will get a small pop up titled "launch application" asking if you wish to use "streamtorrents" as the preferred application to open the linkl you clicked on in the previous step. Click yes.
At this point you want to focus on the TWO streamtorrents software windows that are active. One window will appear to be a web page not connected.. suggesting you can refresh. DON'T do anything. Look at the bottom of that same window and you will see that the page is still loading (buffering). Give it a minute or so and the blank white page will disappear. You will have an advertisement free stream of your game of choice. The OTHER window is monitoring the channel you selected and allows you to save favorite channels, etc.
This is my preferred means of watching NFL these days. Let me know if it works for you. Be sure to bookmark the
http://www.myp2p.eu/competition.php?competitionid=&part=sports&discipline=americanfootball site so you can come back to it week after week and find what links are up and running for your game of choice!
