Keep in mind that you can buy the Center Ice, Extra Innings, etc through the league websites. For many people, this is a better option, as you don't have to be in front of your TV to watch a game.

If you have a newer TV, you may be able to hook your laptop, tablet, or phone up to the TV to watch those games on your TV.

However, please keep in mind that you will not be able to see your "local teams" (as defined by the leagues) on those packages. You'll still need to go to a TV to see those games.

MLS and NHL repeats are not blacked out on the HD Premium Tier. I'm not sure about NBA repeats, but I do know that MLB repeats are blacked out.
