If one with AEP wants Big 10 Network (although there is a note on this one in terms of location), ESPN Classic, Fox Sports San Diego, PAC 12 Network, MLB StrikeZone, NFL RedZone, Universal Sports Network, and additional RSNs, etc. then one would need MultiSport to get them.
Otherwise, Fox Sports 2 and BEin Sport are in AT250. (Tennis Channel along with The Outdoor Channel and The Sportsman Channel are also included in this package.)
AT200 has FXX, NBA TV, NFL Network, MLB Network, and NHL Network. (Fox Sports 1, Golf Channel, Univision Deportes Network, and NBC Sports Network are also in this package.)
AT120 Plus includes any regional sports networks available in the sub's area.
(AT120 includes ESPN, ESPN 2, ESPNews, and ESPN U.)
[BEin Sport and Fox Sports Deportes appear to be in all Dish Latino packages. ESPN Deportes, Univision Deportes 2, and Univision Deportes Network are in the Clasico package. FXX, MLB Network, and RSNs are in Dos. Fox Sports One, ESPN, ESPN 2, and ESPNews are in Max. I believe I read here that Tennis Channel is in Max but cannot confirm it.]
{Dish America has ESPN and ESPN 2. Dish America Silver has Golf Channel, MLB Network, NBA TV, NFL Network, and NHL Network. Dish America Gold has NBC Sports Network and Tennis Channel. I am unsure if Dish will or has moved NBC Sports Network due to the AT250 to AT200 change. I am also unsure if Dish America Silver contains RSNs, but I think it does or at least used to.}
* With all that said, I believe the minimum packages to add MultiSport are America's Top 120 Plus, Dish Latino Dos, and Dish America Silver as these would already have RSNs from my understanding. Also, FXX is probably still included since it was Fox Soccer Channel before if anyone was confused on why it is still included.
