Given that it’s a week we’re dedicating to offensive lines and linemen, it seems appropriate that we bring back an old favorite to show which linemen are the most efficient when it comes to pass protection; Pass Blocking Efficiency (PBE).

It’s a simple enough formula. We weigh hits and hurries as worth 75% of sacks, add the three forms of pressure up, divide it by the number of times they pass blocked at a certain position and you’re left with your PBE number. For the mathematically inclined, it looks a little like this:

(1– ((Sacks + (0.75*(Hits + Hurries))/ Pass Blocking Snaps))*100 = PBE Rating

Looking at all offensive linemen who played at least 200 snaps as tackle (note, only snaps at tackle are counted), let’s see which of the 75 guys who qualified impressed the most over the course of the regular season.

More Than was Bargained for

By the end of the season, the St Louis Rams had fielded four players for at least 200 snaps in pass protection at tackle. Former first round pick Jason Smith could only finish 41st after giving up two sacks, two hits and 11 hurries on his 201 snaps in pass protection. The highly-touted Rodger Saffold was down in 65th after surrendering 32 combined QB disruptions on 359 pass blocks. Even swing lineman Adam Goldberg could only finish 47th when he filled in at tackle. No, the only Rams lineman that impressed at tackle in pass protection was actually Harvey Dahl. Not only did the former Falcons guard outplay his teammates; he outplayed everyone. The sample size is limited, and he was helped somewhat by playing in an offense that attempts to get rid of the ball quickly, but on 200 snaps in pass protection Dahl gave up just three hits and three hurries, giving him a league-best PBE rating of 97.8. So, while the Rams look at ways to rebuild their line, their use of Dahl could be something to watch.

The Blind-Siders

While you can look at Dahl’s 200 pass blocks and think the sample size skews the data, you can’t say the same thing about the men that follow him. Joe Thomas is widely regarded as the finest tackle of his generation and finishes second, just ahead of Andrew Whitworth who gave up one less pressure, but was in pass protection at tackle for 72 fewer snaps. Neither man covered themselves in glory in the run game, but a franchise left tackle first and foremost should keep their quarterback upright, and you can’t deny that either man excelled in that regard.

The Front-Siders

While Thomas and Whitworth have been protecting their QBs’ blindsides, the top tackle over the course of the season when it comes to protecting the front side was the Tennessee Titans’ David Stewart. He gave up 19 combined sacks, hits and hurries on 547 pass blocks to beat out Jason Peters (a left tackle for the left-handed Michael Vick) who gave up 21 on 570 snaps in pass pro. The interesting thing about Stewart is who his quarterback is; Matt Hasselbeck. Whatever you may say about Hasselbeck he is one of the best quarterbacks in the league in making his offensive line look good, getting rid of the ball before pressure really has a chance to get to him. It showed this year with Stewart ranking atop the front-side tackles, and it showed last year when his front-side tackle Sean Locklear finished at the top of the rankings.

The Free Agents

That gives you the Top 5, with the soon to be available Demetrius Bell just outside in sixth after giving up one sack, one hit and seven hurries on the 237 occasions he was trying to keep Ryan Fitzpatrick clean. He leads all the available free agent tackles. The interesting thing to note is how some of the players who didn’t have the requisite number of snaps in pass protection came out, particularly Jared Gaither. In his time at San Diego, Gaither gave up just three pressures on 165 pass blocks which would have led the league, though you could say something similar about Anthony Collins of the Bengals. He spent 80 snaps in pass pro at tackle and gave up just the one hurry; a trend whenever Collins has seen the field in recent years.

The Rookies

Over the past few years we’ve seen plenty of rookies come in and struggle. It’s one of the things that made Tyron Smith and his debut season such a joy to behold (except for when Jason Babin was lined up opposite him). He finished 14th overall after giving up eight sacks, a hit, and 21 hurries on 620 pass-blocking snaps. Incredibly, that wasn’t enough to lead all rookies after Marcus Gilbert gave up nine fewer QB disruptions on 167 fewer pass blocks. Smiths’ run blocking set the two apart, but it’s got to be reassuring for Steelers fans that they’ve found someone who can help Ben Roethlisberger stay healthy.

It's interesting to see Andre Smith on that list. Having not heard of him since the Smith vs Smith draft other than that he as monstrously overweight, I had assumed he was a bit of a bust. That assumption at least made me take comfort in the fact that both Smiths busted and we were in a lose-lose situation with either of them. Now it's clear that Billy D and Spags were just flat out wrong.

Thankfully, Jeff and Les will get it sorted.

I dont think you can proclaim Andre Smith a stud because he is on this list. Saying Billy and Spags were wrong on him isnt fair either. Would you have seriously considered this guy, considering our draft slot:

Not a chance

Thanks for the post X. Very interesting. Im surprised we havent heard many rumblings about a full time switch to OT for Dahl, but I wonder how well he graded on tape compared to statistically.

Teams were definitely exploiting the left side of our line at the end of the year. How much did he benefit from that?
