Luchametric MLS Power Rankings: May 20, 2011

We've updated the Power Rankings for the first time this season.  We love a single table, but because there are so many differences among the teams in terms of how many actual games they've played, even a single table distorts their relative strengths, making things rather confusing.  Points per game gives you a bit of a better sense of who is playing well, but our statistical measure, which takes in a number of weighted variables, provides an even better measure of the differences (in our opinion). 

RSL is on top, which is as it should be.  At 2.29 Points per game they are playing extremely well by any of the traditional measures used to rank teams (Points and PPG). Notice that the Z-score for the LM indicates that a Big Four has emerged this season, at least to this point, with RSL, New York, Dallas and Los Angeles all at 1.0 standard deviations or higher  above the mean. Notice also that four clubs (Toronto, San Jose, Vancouver and K.C.) are as bad compared to the rest of the league as the top four are better. 
Hmmmmmm, perhaps the parity that used to characterize the league is finally gone. We'll see.  In any case, Crew fans can take comfort in the fact that our measure puts them above where they are in the single table, reflecting how disciplined and organized they've been thus far (except at San Jose).  Now if we could only start scoring some goals...
