Wayne Gretzky's trade to Kings was an icebreaker for NHL

And it happened exactly 20 years ago today.

Yes, it has been two decades since the Edmonton Oilers celebrated winning the Stanley Cup by trading one of the greatest players in hockey history. That's showing 'em.

As for Gretzky, his legacy grew from fantastic hockey player to fantastic pitchman, because the Kings reached the 1993 Stanley Cup finals, the NHL learned it could expand because of its newfound popularity in the so-called Sun Belt, and nontraditional hockey markets started springing up.

There's probably never been another NHL trade with greater impact.
