You must be spanking new to Sat television. The good ole days of watching wild feeds of MLB, NHL, etc... games for "free" have long since passed. The "sports pack" is a bit misleading as you really only get to watch unimportant stuff on them and regional college sports on the RSNs.
You can only get your local games, and those shown on national networks (TNT, ESPN, TBS, etc...). If you want the remaining games, you need to get the appropriate sports "ticket" at about $200 a season.
What about all the Fox channels that are from 400-438. Such as Fox Sport ohio, fox sports north, fox sports south etc.... will these channels have nfl games on during the season? I know some have had pre-season games.
Pre-season is not the regular season. In my limited time on the planet, I've never seen RSNs show NFL games. Fox, CBS (back in the past NBC) pay beaucoup bucks to have the rights, not RSNs.
I feel terribly awful if you thought that all of this stuff was going to be available to you for $7 a month because it isn't anywhere near that cheap... and you can't even get the NFL Sunday Ticket on Dish to begin with.
