Just so I've got this straight: All of the World Championship games are available in the US through ESPN+, an $11/mo. streaming service that can be purchased on its own or as part of a discounted streaming-service bundle that includes other popular services such as Hulu and/or Disney.
EXCEPT for the WC games featuring Team USA and Canada, which are only available in the US through NHL Network, a third-tier sports channel that does not have its own streaming option, and is only available through outdated/bloated cable, or Fubo/SlingTV (which, IMO, are lesser streaming-cable services when compared to YouTubeTV and Hulu Live, but YMMV). AND, even those limited cases, NHL Network is not part of the normal packages (which generally cost from $40-$120/mo.), but only available as part of a $10-$12/mo. sports package add-on that is bundled with a bunch of garbage.
Does that sound about right?
