The great thing about places like Las Vegas and Dallas and Florida and Nashville doing so well on the ice is that they are buildIng/have built passionate fan bases of their own.
Chicago has been such a great hockey town for so very long with so many energetic fans that this is just part of the long-time fabric of the City. From the great teams of the 1930s to the Bobby Hull and Stan Mikita and Glenn Hall era of the 1960s to the Cups won several years ago. Chicago simply loves hockey.
And now that kind of fever had taken root in the Nevada Desert and in the warm and balmy breezes of South Florida and the crowded Metroplex of North Texas and in Music City in Tennessee. A great sport that now has strong roots from SoCal deep into Canada.
The NHL playoffs are great for many reasons including the fact that these guys play real DEFENSE, too. Something the NBA decided to forget about years ago. And their product has suffered for that. On the ice it is all-out... every second.
The only places where hockey has had trouble gaining traction have been in Arizona and in Atlanta. And neither of them will see NHL teams for a long time, if ever.
Adding Houston one day would be sweet. A natural rival for the Stars. And maybe some day the NHL will try Kansas City again.
