Earlier this offseason, we discussed the fact that the Pittsburgh Steelers have had among the best offensive lines in football, centered around their high reliability in pass protection. Pro Football Focus published a list back in April ranking every offensive line based on their pass-blocking proficiency, which is essentially the percentage of time that the line as a whole allowed pressure, with sacks weighed more heavily than hurries and hits. They ranked first on that list with a pass-blocking efficiency rating of 89.7.
Yesterday, they published an interesting follow-up study that ranked the offensive line on the same criteria, only isolating it specifically for long-developing plays that took at least two and a half seconds from snap to pass, and the result may surprise you—initially.
