If this is still going, I want you to check out this information OP. Washington, over the last 3 seasons, is quite mind-boggling.
On a side note, Washington clearly has some sort of voodoo magic going on. Over the past 3 full seasons, at 5V5, their GF% is 56.57%. The next best team is Tampa, at 53.78%, and every other team is within 1% of the team above and below them. (Except Buffalo is dead last and 1.76% lower than the 30th place Canucks.) Their PDO is 1.019, next best is Minnesota at 1.011 and every other team is within 0.005 of the next team above and below them. Their HDCF% is 48.22% which is notably lower than their CF% and SF%. This tells me that HDCF is a complete failure at judging whether or not a team's shots and chances are actually dangerous or not.
There is clearly more to hockey than some of these stats are telling us. And statistics like Corsi (which, BTW, I love) are clearly diminishing in effectiveness from the times that Washington and LA were ranking 1st in it and then destroying everybody.
If Trotz can bring up NYI to a 1.02 PDO, and Washington falls below 1.01 (At 5V5), while no other metrics (such as xPDO, xGF%, CF%, HDCF%) can make sense of this, then I think that these statisticians need to watch hundreds of Barry Trotz games and figure out what he’s doing, and then develop a new xGF% model.
