Wasatch Soccer Sentinel

16 out of 18 sites published for match days 13-14. US Soccer Players has been dropped after they let me know they are not continuing with their monthly article. Rankings are for both midweek games played on May 17th, and Saturday May 20th.

A reminder of what Power Rankings should be (not that every site does, of course):

"If two teams played tomorrow, given their current injury concerns, form, and other considerations, who is likely to win on a neutral field? All things being equal, who is the best team going forward, based on what we know now?"

— Richard Farley, NBC Sports ProSoccerTalk. March 11, 2014.

You may notice the inclusion of 'analytic' sites; they serve to function as a 'control group' to others which are based on opinions. There are also sites included that some will argue are 'prediction rankings' - but that also is a form of Power Ranking (see the quote at the top) since it uses algorithms to calculate a team's likely final position.

Bias for or against certain teams are sometimes an unfortunate feature of power rankings. It can be based on their analytic formula, or the raters preference. In some cases the bias can become extreme - If you feel a site got the ratings wrong for your team I invite you to contact them regarding it. Bias ratings for every site are listed below.

I will typically only remove sites for two reasons.

1. Duplicating / copying ratings from another source on the list.
2. Failure to update for 6 consecutive weeks. Previous ratings will not be removed, but new ones may or may not be added. I will still periodically check them to see if they have resumed.

All the averages use the Olympic method (I.E. Truncated Mean value) of dropping the highest and lowest scores, and then averaging the rest to reduce bias.

The full spreadsheet is here.

• Highest Standard Deviation: CF Montreal 5.82
• Lowest Standard Deviation: Los Angeles FC 0.34
• Biggest Rise: CF Montreal up 6
• Biggest Fall: Minnesota United down 6

BIAS RATINGS No site can be perfectly on average all the time, every site will naturally have a bias for or against all teams.
