Tilman Fertitta, owner of the NBA’s Houston Rockets, said last week he is “very interested” in the possibility of bringing the NHL to Houston. “But it will have to be a deal that works for my organization, the city, fans of the NHL throughout the region and the NHL Board of Governors,” he said in a statement. “We are in the very early stage of evaluating what opportunities may exist but look forward to a thorough process.” At the very least, the possibility gives new leverage to owners who want new arenas, such as Calgary and Ottawa. Houston also could become a relocation option for the New York Islanders, if they don’t get a new arena at Belmont Park, and an option for other unstable franchises. Houston was home to the World Hockey Assn. Aeros and had a minor league team until 2013.
