Jaguars Offensive Line: Where do they rank on Football Outsiders?

I'm sure many of you are familiar with Football Outsiders and the kind of analytics they measure. We've used them before and looked at their previews for the Jacksonville Jaguars and also looked at various stats they measure. Today, we're going to look at how Football Outsiders ranked the Jaguars offensive line.

First, an explanation of how these stats are derived:

Teams are ranked according to Adjusted Line Yards. Based on regression analysis, the Adjusted Line Yards formula takes all running back carries and assigns responsibility to offensive line the based on the following percentages:

  • Losses: 120% value
  • 0-4 Yards: 100% value
  • 5-10 Yards: 50% value
  • 11+ Yards: 0% value

These numbers are then adjusted based on down, distance, situation, opponent, and the difference in rushing average between shotgun compared to standard formations. Finally, we normalize the numbers so that the league average for Adjusted Line Yards per carry is the same as the league average for RB yards per carry. These stats are explained further here.

The following stats are not adjusted for opponent:

  • RB Yards: Yards per carry by that team's running backs, according to standard NFL numbers.
  • 10+ Yards: Percentage of a team's rushing yards more than 10 yards past the line of scrimmage. Represents yardage not reflected in Adjusted Line Yards stat.
  • Power Success: Percentage of runs on third or fourth down, two yards or less to go, that achieved a first down or touchdown. Also includes runs on first-and-goal or second-and-goal from the two-yard line or closer. This is the only statistic on this page that includes quarterbacks.
  • Stuffed: Percentage of runs where the running back is tackled at or behind the line of scrimmage. Since being stuffed is bad, teams are ranked from stuffed least often (#1) to most often (#32).

Got all of that? Yeah, me too. Anyway, to the important stuff:

 Fancy, right?

As we all know, the Jaguars were very successful rushing the football and not that successful passing the ball. The Jaguars ranked 3rd in the NFL in rushing and 27th in passing, and these rankings just hammer that home. That's kind of what we already knew, however.

Aaron Schatz from Football Outsiders was on with Pete Prisco on 930 The Fox discussing some of these rankings. He specifically made mention that the Jaguars offensive line improved quite a bit when left guard Justin Smiley was replaced in the lineup by Vince Manuwai, especially in the run game. Schatz also touched on the low pass blocking rankings and made mention that realistically they could be higher, but David Garrard tends to lend himself to more sacks because of his play style. Notably, he takes sacks and tends to hold on to the football.

Football Outsiders digs a bit deeper in the running game, breaking down where the teams run. Unsurprisingly, the Jaguars were a left-handed running team, chosing to run predominantly from center Brad Meester to left tackle Eugene Monroe. The Jaguars Adjusted Line Yards (ALY) on the left end was 4.70 (ranked 8th), left tackle 4.75 (ranked 5th), and mid-guard 4.63 (ranked 3rd). The right side wasn't horrible, but wasn't as stout as the left aside from running outside the right tackle. The right tackle came in at 4.26 ALY (ranked 13th) and the right end at 4.78 (ranked 6th).

Football Outsiders then breaks down where the team actually ran, percentage wise.

JAX 421 14% 4% 64% 5% 12%

Again, this shows the Jaguars ran predominantly up the middle and to the left side. I assume quite a bit of that had to do with having Vince Manuai on the left side, and lack of Eben Britton on the right. Only the Miami Dolphins and Buffalo Bills ran more or the same percentage of their carries up the middle than the Jaguars. The Jaguars were 14% higher at the MID/GUARD level than the NFL average of 50%.

This really doesn't tell us more than we know, all it does it put numbers down to confirm that the Jaguars are in-fact a power running team offensively. The amount of carries up the gut too, makes me lean more towards the thought of adding carries to Rashad Jennings workload. The last think Maurice Jones-Drew needs with questions about his knee is more pounding up the middle of the offensive line.

At least the MID/GUARD percentage was down from 2009, when it was a whopping 76%!
