Three years after the arrival of the AJHL, another league, the Western Canada Junior Hockey League was formed. It was considered a "rebel league" by the Canadian Hockey Association, and thus not permitted to play for the Memorial Cup. The seven team loop featured five teams that defected from the Saskatchewan Junior Hockey League along with the Edmonton Oil Kings, and an expansion team for Calgary, the Calgary Buffaloes. The Buffaloes were dismal in the league's inaugural season in 1966–67 season, finishing just 4-47-5. The franchise renamed itself the Calgary Centennials the following year, and had moderate success in the mid-1970s, winning three division titles and reaching the league finals once. It relocated to Billings, Montana in 1977 to become the Billings Bighorns. That franchise continues today as the Tri-City Americans. Future NHLers John Davidson, Bob Nystrom and Mike Rogers played for the Centennials.
