Fantasy Football Week 12 Tiers

Week 12 byes: Carolina, Pittsburg


In this fantasy football model, I take aggregated expert ranking data from and pass it into a statistical clustering algorithm called a Gaussian mixture model.  The algorithm finds players who are ranked similarly and discovers natural tiers within the data. The results is a series of simple charts that can help you decide your fantasy football line up each week. Match ups, injuries, strength of offense and defense are all accounted for. For more intuition behind the model, you can read this introduction.

(2) Favor higher tier players. 
(3) When choosing between players of the same tier, flip a coin or go with your gut. If experts are 50/50, there's no telling.

Rest of Season

ROS: QB - RB - WR - TE - K - DST


(1) Why are the flex charts inconsistent with the RB and WR charts?
This happens because flex is an after thought for many experts.  Less experts submit rankings to Fantasypros, and they're not graded on them. Flex tiers are always one of the more debatable charts.

(2) How accurate are these tiers?
Here is a link to last year's accuracy.

(3) When do you update the charts?
Every day. Check the last updated timestamp.
