I know some of you don't like PFF's grading system, but here it is. This one grades the tackles for pass blocking efficiency. Big news. Free isn't the worst, very close though. https://www.profootballfocus.com/blog/2012/11/28/sig-stat-snapshot-pass-blocking-efficiency/ What are numbers without context? That was the driving force behind our signature stats section and it’s why I’m able to write about things like the Pass Blocking Efficiency. It’s a simple enough concept. If you judge an offensive linemen just by how many times they get beaten for a sack, then you’re really not judging them at all. You need to take into account how much total pressure they give up, how many snaps they’re in pass protection for, and how quickly the pressure comes. Now this stat doesn’t take into account how quickly the pressure comes (that’s what our grading is for), but it does the other things so I can, without any doubt, say that this stat beats all the others when it comes to measuring the performance of offensive linemen in pass protection. The formula is simple enough. You add all sacks with three quarters the worth of hits and hurries, divide by snaps in pass protection, take away from 100 and just like that you’ve got an efficiency formula.
