The next season Goring was promoted for good to the NHL, and starred for nine seasons for the Los Angeles Kings, developing into one of the most complete players in the league. In the 1975–76 playoff quarterfinal series against the Boston Bruins, Goring scored the overtime game-winning goal in game 2 and game 6. He won both the Bill Masterton Trophy and the Lady Byng Memorial Trophy in 1978, becoming the first player to win both trophies the same year. Prior to the 1978–79 season he was offered a five-year, $1-million contract by the World Hockey Association's Edmonton Oilers; Goring re-signed with the Kings after they countered with an offer of $1.25-million over the same term.
