Duck here, just trying to help anyone out:
I have used ESPN3 tons, the last many years. From what I can tell, ESPN changed it last year. It used to be all ESPN3 games were free to all. Now, from what I can tell, some games are still, but other hot games are not, they are locked. And to get in to see those locked ESPN3 games, one needs to have a TV provider that is in bed with them. One just simply enters their TV provider's id and password, Comcast for me in my personal case.
But to let all know, while those that do not have cable TV or such, one can still see any game for free online. You may not be able to view it on your smartphone if you do not have a good TV provider, but you can still view games for free online. Many sites out there. But "first row sports" always has all games online. Even though I have a spendy cable package, I still use first row sports, cause I like watching 3-5 games at a time on my computer, covering the most CFB games I can. How do you get there. Just google, "first row sports eu". They got bused by the FBI last year and had to change their domain to Europe servers. But they changed it a year ago and it is a pain in the butt to try to use unless you really know what you are doing.
Basically You google it, as I said. Then the first link(or any of the top google links will take you to it, or their mirror sites. DO NOT DOWNLOAD their little app that it tells you you need. It is with spyware- as i tested it and know. You go to their site, click on "American Football" and then pick your game out of the list. But be warned, you will get TONS of spam browser windows popping up. Just close those windows. And then you have to wait 30 secs,,,,,, and then the trick is finding the little "x" to close those spam advertisement windows out. If you click the wrong one, again, more spam browsers will open up. It takes time getting used to, and patience, skill, but once you get used to it, watching any CFB(or NFL) game is really easy, for free, online, and a guy not having to pay for cable or any TV service. And remember, do not click on those fake red x's. One, after practice, can tell what is a real x and a fake one. And remember, you do not NEED any App that whatever site is telling you need to watch a game. Those are tricks, tricks for spyware. DO NOT DOWNLOAD ANY APP THEY OFFER YOU. They lie and tell you that you MUST have their app. Nonsense, just grow wise, be patient, and click through all those stupid advertisement blockers.
And ya, justin TV is good too. But many network providers complain to justin and most often a game gets shut off mid-game.
Any questions, just feel free to ask me.
