250th on the list of all time NHLers? That's still a tiny percentage of all players that have every played (~1500/year, obviously with some overlap from year to year). And that's only counting those in the NHL; there are many hockey "pros" who could only dream of making the NHL. Factor them in and the Gretzky performance is even more remarkable.

And you're only looking at points scored. How does a star's leadership affect their team? How did their mere presence affect the other team's entire strategy? How many seats does a star fill in the stadium every time they played? How many jerseys and other merchandise did they sell? Hockey, like software, is a business and I'd be that someone like Gretzky brings in an order of magnitude more money than an "average" hockey pro.

Denying the possibility that there could be someone 10x better than you is the real ego stroking. I know there are developers an order of magnitude better than me. I find that inspiring, as it gives me something to work for every day.
