Offensive line rankings: Which players are affected the most in fantasy?

NOTE: The rankings in this column have been updated since its original publish date in June.

Hall of Fame general manager Jim Finks once said, "A running back in the NFL is only as good as his blocking will let him be." This same rule applies to the passing game, as quarterbacks had an abysmal 29.1 Total QBR last season on plays in which they were under pass rush pressure.

Despite its importance, the fantasy football world has a significant gap in measuring the impact that blocking has on fantasy production.

That's about to change, as I have put together new blocking grading system designed to help fantasy owners identify the impact each team's offensive blockers are likely to have on fantasy prospects during the 2017 campaign.
