The WHA ended the NHL policy of paying its players only a fraction of the league's profits and, combined with the abolition of the reserve clause, led to much higher player salaries. Many great stars began their careers in the WHA, including Mark Howe, Wayne Gretzky, Mike Gartner, Mike Liut, and Mark Messier, who was the last WHA veteran to play in the NHL; he opened his professional career with 52 games with the Indianapolis Racers and Cincinnati Stingers in 1978–79, and played his last NHL game on April 3, 2004. The final active player and official in any on-ice capacity for the league was referee Don Koharski, who started as a linesman for the WHA and retired at the end of the 2008–09 NHL season.
