In about two hours I am going to post Win Charts for every single NBA team for the 2010-11 season. In order to get anything from these charts, you have to have a point of reference.
In order to provide said reference, I borrow an idea from my favorite baseball website, Fangraphs.com. Fangraphs recently posted a “Statistic Percentile Chart“. I found the chart exceptionally useful. Now I know, for instance, how to interpret Prince Fielder’s slugging percentage (actually, I sort of knew before, but not in such detail).
Hopefully my MWS chart will be just as useful to you and will provide the same sort of reference point. BTW, I also have the chart posted as a permanent page on this website.
Two quick points to be made about the results of the chart.
One, if you notice, a winning percentage of 0.500% is not the NBA average. Slightly more than 60% of all qualifying NBA players post winning percentages below 0.500%. That’s why I call my value statistic “Wins Above 0.500%” rather than “Wins Above Average”. “Wins Above Average” is not semantically correct, and can be misleading.
Which leads to my second point. When I did my chart I calculated the median point for NBA player winning percentages. It is what we estimated it was, right around 0.420%, meaning half of the NBA posts percentages above that number, half below. Thus a team filled with median level players would be expected to win around 34.0 games.
