All but one published (the NWSL site which has apparently stopped doing them) for week 21, and every site but one had the exact same rankings (the last just flipped the order on two teams)!
As always, if you know of a site I have not used please let me know in the comments and I’ll look into adding it!
Sites Used
- Five Thirty Eight (Projected Pts.)
- Soccer Club Stats (Win League %)
- Backline Soccer
- Reddit/r/NWSL
- RSL Soapbox (Earlier this week on this site)
- NWSL - No Ranking Wk. 14-22
- Freeborg Power Index
You may notice the list includes ‘analytic’ sites; they serve to function as a stable counterbalance to the rest which are based more on personal opinions, and those done by ‘team’ blogs’. There are also included sites that some will argue are really ‘prediction rankings’ - but in reality isn’t that what a Power Ranking is (see the quote at the top).

Site Bias
All sites are going to have bias, whether conscious (blogs) or due to analytic calculations (based on past performance for example). This section lets you see the extent that sites are biased for/against teams.
