He became the league's preeminent star, winning scoring titles in 1970 and 1971 and adding a record 122 points in 43 playoff games.

[3] Dionne's scoring feats were marred by one of the most infamous events in Canadian junior hockey during the 1971 Richardson Cup finals against the Quebec Remparts.

Following a riot in Quebec City after the penalty-filled fourth game of the series in which Dionne's Black Hawks' team bus was attacked by the mob,[4] the fifth game was played at a neutral site, and the remainder of the series was not played due to fears of further violence.

Dionne played his first four seasons with the Red Wings, where he was one of the few stars on an otherwise stagnant team that failed to make the playoffs.

The owner of the Los Angeles Kings, Jack Kent Cooke, offered Dionne $300,000 per year.

[7] During Dionne's time with the Los Angeles Kings, he played eleven and a half seasons and formed the famed "Triple Crown Line", centring Charlie Simmer and Dave Taylor.

He took eventual Calder Trophy winner Luc Robitaille, Jimmy Carson and Steve Duchesne under his wing.

As a fundraiser for the Juvenile Diabetes Research Foundation in 1979, Dionne, Simmer, and Taylor recorded a song written by Alan Thicke, "Please Forgive My Misconduct Last Night," which appeared as the B side of "Hockey Sock Rock" by Phil Esposito and some of the New York Rangers.

Despite the rapport with the rookies, there was also a falling out with coach Pat Quinn; moreover, the aging Kings were on track to miss the playoffs.

[10] He has maintained a large business and investment portfolio since his playing days, owning the Blue Line Diner in Niagara Falls, operating a sports memorabilia store in Buffalo and buying and selling real estate.

Dionne's younger brother Gilbert also played in the NHL and won a Stanley Cup with the Montreal Canadiens in 1993.

Prior to the start of the 1993–94 season, Dionne helped to create local interest in the ECHL's newest franchise, the South Carolina Stingrays.

With the help of some young players, Dionne gave an on-ice demonstration of the rules of hockey to the southern audience.
