The fantasy football world has lagged behind when it comes to effectively measuring the impact blocking has on fantasy production, so last year, I devised a grading system that uses multiple advanced metrics to project how blocking matchups will impact fantasy football performance in the upcoming week's contests. (The details of the system can be found here.)
The entire list of the Week 9 overall matchup grades are posted below, along with a detailed look at how those blocking grades could impact certain start-sit decisions this week. Subjects here include whether fantasy managers can trust Peyton Barber in a starting lineup, if the Packers can find the fantasy upside against the Patriots that they couldn't find versus the Rams last week, if Kenyan Drake's recent production burst is the real deal and if Adrian Peterson will be a boom or bust candidate and more.
(Note: The metrics and rankings listed below are for Weeks 4-8).
