New! U10 Rankings
After considerable research I have decided to publish rankings for all U10 teams. This ranking system was established to help tournament organizers fairly flight their competitions and thus give the players a better experience. U10 teams travel to tournaments. In the past another site drew some flack for ranking such young players. With your help the U10 rankings can be as predictive as for the older age groups using my algorithm. They are meaningful. A common concern is that the kids are too young and coaches should be focused on developing skills instead of winning. My view is if a coach isn't developing his players then it is quite simple: he is a bad coach and you should move your player to another team. This has nothing to do with the rankings! Please don't get me started on leagues that don't post their results. Enjoy!!!
If your team is missing you can view unranked teams here.
A ranking systems' accuracy is measured by its "Predictive Power" (how often a higher ranked team beats a lower ranked team). A Predictive Power of 0% is equivalent to flipping a coin. 100% means the rankings always predict the result of a game (impossible given the random nature of the sport). Some ranking systems only rank the top 25 teams in each age group. That is not helpful if you are trying to flight a tournament. "Coverage" is the fraction of all games where both teams are ranked by the ranking system. Here is how the online ranking systems compare today:
This site ranks 79,000 youth soccer teams in the USA based upon the results of 245,000 games played since August 1st 2016. The results come directly from more than 350 different tournament or league websites and are the most accurate and complete set used by any ranking system. The rankings are based solely on team results. Every goal in every game is considered when calculating the ranking of each team. Each team is assigned a score that is measured in goals. To predict the goal difference when two teams play each other simply subtract the score of one team from the score of the other. For example, if Denver Rovers (35.6) plays Parker Stars (33.5) then you can expect Denver Rovers to win by about 2 goals. This works across age groups and even when girls play boys!
The rankings are recalculated almost every day, so please check back often. Teams are only listed if they have played 10 games. Sometimes games are split between duplicate teams. I try to fix as many of those as possible. If you spot anything that looks wrong please drill into the team details and click "Report Errors" (at the top right of the screen).
I still need to load results from the following sites: www.thepremiereleague.com, www.illowa.org, www.bays.org, www.mnyouthsoccer.org, lijsoccer.com.
Let me know if you spot anything else!
