The expansion Vancouver Grizzlies of the National Basketball Association were one of the anchor tenants of GM Place upon its completion in 1995, but moved to Memphis, Tennessee after just six years of operations in Vancouver. Professional basketball has been rumoured to return to Vancouver, most recently in the form of the Vancouver Dragons of the Continental Basketball Association, but has yet to establish itself. Vancouver continues to have a huge interest in acquiring a full-time National Basketball Association team and having them play their home games at Rogers Arena. Vancouver has also had professional lacrosse (Vancouver Ravens, National Lacrosse League, 2001-2004) and roller hockey (Vancouver Voodoo, Roller Hockey International, 1993-1996) teams. The Vancouver Blazers of the World Hockey Association played in the Pacific Coliseum for two seasons (1973/74 and 1974/75).
