You may notice the inclusion of ‘analytic’ sites; they serve to function as a ‘control group’ to the rest which are based on personal opinions. There are also sites included that some will argue are ‘prediction rankings’ - but that also is a form of Power Ranking is (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.

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.

Site Bias

All sites are going to have bias, whether conscious (blogs) or due to analytic calculation (based on past performance). This section lets you see the extent that sites are biased for/against teams. Negative totals (-) are bias FOR, positive numbers (+) are bias AGAINST.

This bias list is based on Season Average and not weekly ranking.

• Most accurate site of the week: 538 with 13 teams exactly on average.
• Least accurate site of the week: Betting Odds average on 3 off tiebreaker with ESPN.
