The reason I wouldn't count RSNs is because they aren't available to everyone. Nobody can have every one of those channels, so why count them in a total? Just my opinion of course.
They are available to everyone. Just like premiums, you have to subscribe to them.
Blackouts, Well you can find them on TBS ,MLB,and just about any channel showing pro games.
Just so happens the Rules make it impossible to view out of Market PRO Sports games.
Not really the Providers fault.
But with D* you have an option for $200 per year($16.67 per month) to watch as many out of market Pro Baseball games you want in SD and HD.
Not Really that bad of a deal considering you Pay $12.99 for just the Sports pack and get Nothing.
And E* RSN's well they don't show anything.
