Wayne Gretzky was traded from the Edmonton Oilers to the Los Angeles Kings in one of the most controversial player transactions in ice hockey history.

Wayne Douglas Gretzky is a Canadian former professional ice hockey player and former head coach. He played 20 seasons in the National Hockey League (NHL) for four teams from 1979 to 1999.

Gretzky is the leading career point scorer and assist producer in NHL history and has more assists than any other player has total career points. He is the only NHL player to total over 200 points in one season, a feat he accomplished four times. In addition, Gretzky scored more than 100 points in 15 professional seasons. At the time of his retirement in 1999, he held 61 NHL records: 40 regular season records, 15 playoff records, and six All-Star records.
