The fantasy football world has lagged behind when it comes to effectively measuring the impact blocking has on production, so I devised a grading system that uses multiple advanced metrics to project how blocking matchups will affect performance in the upcoming week's contests. (The details of the system can be found here.)
The entire list of the Week 15 overall matchup grades are posted below, along with a detailed look at some of the favorable and unfavorable blocking matchups fantasy managers should be aware of and how those could have an impact on their start-sit decisions.
(Note: Unless otherwise noted, the metrics and associated rankings detailed below are from Weeks 9-14).
