Much is made of the NHL's expansion from six to twelve teams in 1967. In one bold stroke the league broke out of its post-war small-league policy and caught up to other major league sports that had been spreading out across the continent for ten years. It was the era of exponential growth, so there was amazement but not outright bewilderment when major league hockey doubled in size again in 1972, from 14 to 28 teams. Twelve of the new clubs came courtesy of the upstart WHA, and the other two were in large part chess pieces to protect the NHL's position against the new league. The fourteen clubs were the Alberta Oilers, Atlanta Flames, Chicago Cougars, Cleveland Crusaders, Houston Aeros, Los Angeles Sharks, Minnesota Fighting Saints, New England Whalers, New York Islanders, New York Raiders, Ottawa Nationals, Philadelphia Blazers, Quebec Nordiques and Winnipeg Jets. Only six of them made it to the 1980s, and today only two operate with the same logo in the same town: Edmonton Oilers and New York Islanders. But they have thirteen Stanley Cups amongst them, against five for the class of 1967. An AHL club called the Aeros operates in Houston today, in the 18,300 seat building also used by the NBA Rockets. Houston's a natural rival for Dallas. In the light of recent NHL expansion talk we might yet see the Houston Aeros in the NHL.
