It doesn't really 'screw' anyone. You just watch it on NHLN. Just like when it's on Versus or NBC. It's not like when we had to deal with the Metro Channel debacle (before MSG+2) where you had games of all 3 teams that would overflow onto the Metro Channel, but because that was a 'Cablevision exclusive' channel, satellite providers couldn't get it except for out-of-market CI packages. So if you were a D* Center Ice subscriber in NJ, and there was a Devils, Rangers or Islanders game that got bumped to Metro, there was absolutely no way to watch that game. Because the channel that carried it was not available on D*, and it was considered and "In-Market" game under the Center Ice, you were totally blacked out. Now when they overflow it goes to MSG+2, which is available as an alternate on D*.
I don't know if there are any other markets that actually suffer from overflow, so people outside the NY/NJ area might not even know about the problems it causes. (But I don't know if Dish ever resolved their spat with Cablevision, so their NY/NJ subs still may not have MSG/MSG+/MSG+2 at all, and just like Metro, wouldn't be able to get the home feed on CI).. I don't know if you're actually in Flyers territory, but again its the same crap with CSN in the Philly market. You can only get home feeds from CSN Philly on Center Ice if you are outside their territory
The only thing that sucks when it's on NHLN is it's their announcers not your normal home announcers.
