Three of the top four teams in the league in points are also three of the top four teams in PDO, and four of the five teams with the worst PDO can all currently be found in the league's basement. There's obviously something that can be learned from PDO, so what is it?
PDO was introduced by Vic Ferrari a few years ago and while nobody remembers what it stands for, everyone knows how it's calculated. Simply add save percentage to shooting percentage, and you should wind up with a number relatively close to 100.0 (or 1000, as some people prefer to present it). And technically you're supposed to use even-strength numbers only, something we'll skip for simplicity.
While further description of PDO is outside the scope of this article (but can be gained from either Tyler Dellow or Corey Pronman),it's clear to see why PDO is so closely associated with the standings. When we're talking about upwards of 5000 shots for and against per season, even a fluctuation of 1.0 means 50 goals, which is easily enough to knock a strong team out of the playoffs or to push a weak team in.
While it's been previously established that team PDO has a strong tendency to 100.0 due largely to the heavy dependency that shooting percentage has on luck (about 75%), Gabriel Desjardins discovered that the presence/absence of skilled players can sustain a team at a significantly different level for several consecutive seasons. Therefore, it is probably best to compare each team to their established PDO levels instead of 100.0 before predicting jumps or slides.
