That's patently ridiculous. Some goalies are elite, some aren't. Some players are more skilled scorers than others. Some teams have more talent, some teams have better systems, some teams have more injuries, etc., etc. Let's not assume the league is a bell curve.

Still, though, over time we can build up a pretty good idea of the normal range. If a team is putting up numbers that are unprecedented in NHL history then it's a fair bet they are over their heads. So while the idea that the Flames must drop back to 100 is BS, they are certainly outliers and may not be able to sustain it.

In short, I don't think the PDO crowd is necessarily wrong, but they undermine any credibility by a) being too absolute about it, without considering other factors and b) expressing themselves very poorly.

If PDO regressing to 1 is absolute, the only way to win is to shoot more than the opposition. It simply reinforces the fallacy that better corsi equals better team.
