This was their Inagural Season in 1972-1973, their first season in the World Hockey Association, which is now defunct. The Oilers then went on to play in the NHL after the WHA had to merge with the NHL. The Edmonton Oilers went on to become the most successful franchise in NHL history after signing Wayne Gretzky, argueably the greatest hockey player ever, along with Mark Messier, Jari Kurri, Paul Coffey, Grant Fuhr and Andy Moog, winning 5 Stanley Cups from 1984 to 1990 in sports.
