Just saying, if 250th of all-time are about half/a third the p/g of Gretzky, I find the 10x label lacking. Comparing him via pts scored to goalies and defense is questionable at best.
Re-read my reply above. You're comparing a fraction of Gretzky's contribution to a fraction of all the professional hockey players, even if you only look at forwards. Even then, he ends up 2-3x better than this already elite group.
