Great article, I like this adjusted metric. Scoring in different eras is so tough to compare and I don't love it when people just wildly claim Ovie is the greatest because this era is the toughest to score in.
It's always interesting how Gretz comes up too... he's all time goals leader, but people forget he wasn't know for being a goal scorer first, he was a play maker. Doesn't devalue him as the greatest all time player in my eyes though. You take away all of his goals he still leads the league in all time points - but he wasn't the greatest pure goal scorer of all time!
