Goalkeepers after 9

Well, it looks like the fog is lifting. Data are less and less skewed as time passes. Goalkeepers standings and defensive standings for teams after 9 weeks.



How about them Chelsea? Who cares. But WBA, Bolton and Wigan in top ten defenses and Liverpool, Manchester Utd and Aston Villa not. Cold winter is coming, cold indeed for some. I'll refrain from further comment until I look at the strength of schedule so far ( which will be the topic of my next post ) and some other things.

Short explanations: points are negative category, they represent opponents position on current form table X goals you conceded . Two goals from West Ham gets you 40 points, six pack from Chelsea gets you only 6 points. That red 22 for Aston Villa means that their defense has not reached Premier league level thus far since league has 20 teams and their opponent rank is 22. Not really fair but things will straighten themselves by the end of the season.

New feature is OPS+, which is borrowed from baseball. In essence 100 is average and bigger is better. This is development, upgrade of and replacement for my previous descriptive stat ReV and includes ,along with basic goals and saves, replacement level performance, opponents adjustments, park factors, time on the pitch … In short, lot of relevant things. I kept the name same as it is in baseball for the sake of the name recognition. Meaning of the abbreviation is of course different. Soccer has no bases or bats. So OPS+ stands for, I don't know, Overall Player's Score Adjusted ( that's for the + sign ). Yes, I'm reaching here but look at it as an homage to sabermetrics.
