Bottom line: The NHL was scared of signing a 17-year-old. The upstart World Hockey Association was not, and that’s how the Indianapolis Racers secured the rights to Wayne Gretzky when they signed him to a whopping seven-year, $1.75 million contract in 1978.
He only played eight games for the Racers, who were losing a reported $40,000 per game. But Gretzky managed just fine. The Racers sold his rights to the Edmonton Oilers, and he became the leading scorer in NHL history.
“The Great One” is a great example of the arbitrary rules of age in pro sports leagues, because it’s tough to make an argument that Gretzky wouldn’t have been able to play at 17 in NHL, just like he did at 18.
