ESPN+ has the NHL rights for streaming games. (NHL sold the rights to ESPN in the last TV deal.) Cost is about $11 month.
Watch the Hawk games free over the air if you have access to a TV with a high def antenna, as stated in your referenced article.
Games sound like they may be on the local cable providers and DirectTV. Find a bar that has cable or DirectTV.
There are sites like Buffstreams and OnHockey.TV that stream all types of hockey games. Personaly, can't vouch for any of the them.

ESPN+ is subject to blackouts, so no local games. Where I live they blackout Panther and Bolts games, that part is frustrating, however that only accounts for four games.
