Over the past week I have found some free time to update the player ranking algorithm. Not only have I improved the algorithm but I have also fixed a bug/flaw in the code which overly penalized players for giving up short handed goals. The end result is that players who play a lot on the penalty kill should see their defense ratings rise, sometimes quite dramatically. I know there was concern about Lidstrom’s (and others) poor defensive ratings last time so now they are fixed. Lidstrom now gets a very respectably 1.42 defensive rating. You can view all qualifying players rankings by clicking on the appropriate links in the menu on the left.
You will still find some ‘strange’ results in the rankings, like Kobasew’s 3.96 defensive rating, but these will fall off as the players play more ice time. Kobasew gets the high defensive rating because he has had a league low (of players with 350 minutes of ice time) 3 goals scored against his team while he has been on the ice. That’s pretty impressive but probably has more to do with luck than his raw defensive ability. Most of the odd rankings you will find in my rankings can also be found in the rankings recently created by JavaGeek and JavaGeek uses a fairly different algorithm than I do so it appears that those oddities aren’t due to flaws in the algorithm. Generally, ratings significantly over 1.50 are probably not sustainable but overall I am fairly pleased with the results.
