According to what source ?
Some other guy on some Forum ?
PS I don't see it ending on 11/5 on Dish Network, because they have not been able to offer the package. So, if they are still negotiating, then both Dish and NBA have motivation to continue the Free Preview.
The free preview is always for the first week. The season started on the 28th, or 1 week ago. You are also welcome to call Dish Netowrk and they will tell you it's only until the 4th.
Without a contract it could be extended I suppose, but I'm not sure what the motivation of the NBA would be to do that. They charged Directv and the cable companies for the package, so how would it be fair to let Dish continue to show it for free? Also, what possible reason would the NBA care if Dish doesn't show it? Most people will cancel and go to Directv that would have ordered it anyway.
I'm not here to make up stories about Dish, or mislead anyone about league pass. Just to inform people that don't seem to know that the free preview, as of today, ends tonight.
