OFFENSIVE LINES 2005
Regular season totals, playoffs not included
Revised as of 1/7/2006

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 the offensive line 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, and opponent, and normalized so that the league average for Adjusted Line Yards per carry is the same as the league average for RB yards per carry (in 2005, 4.07). 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 that result in (on first down) zero or negative gain or (on second through fourth down) less than one-fourth the yards needed for another first down. Since being stuffed is bad, teams are ranked from stuffed least often (#1) to most often (#32).

NFL averages for each stat given in red.

Why are these rankings different from the team offense DVOA ratings for rushing? Among other reasons, they don't include quarterbacks or fumbles, long runs are truncated, and a different set of adjustments is used, attempting to isolate line play rather than total team offense.

A team with a high ranking in Adjusted Line Yards but a low ranking in 10+ Yards is heavily dependent on its offensive line to make the running game work. A team with a low ranking in Adjusted Line Yards but a high ranking in 10+ Yards is heavily dependent on its running back breaking long runs to make the running game work.

However, it is important to understand that these ratings only somewhat separate the offensive line from the running backs. A team with a very good running back will appear higher no matter how bad their line, and a team with a great line with appear lower if the running back is terrible.

Stats in blue represent pass blocking. Teams are ranked according to adjusted sack rate, which gives sacks per pass attempt adjusted for opponent, down, and distance. Pass blocking stats are explained further here. Our sack totals may differ slightly from official NFL totals depending on the league's retroactive statistical adjustments.

this was good info IMO on how our offense was ran over the seasson

our "stuffed" ranking was 21st .. I thought it would be around 30-32

[Wharton]

Ok so we had the 8th best run blocking o-line and the 32th best pass blocking o-line. Sounds reasonable.

It's strange to me that a line can be in the top 10 in one area but last in the other. Obviously these dudes have some talent and can block. There are quite a few aspects of our pass protection that need to be addressed beyond just the offensive line. Our inability to pick up blitzes and failure to read defenses immediately come to mind.

I'd say the zone blocking system was responsible for the run blocking's success, not talent. Face it, the line sucks.

I agree with you.

I don't know much about the stats on this website,but looking how we don't do well running up the middle makes me wonder(and we all know that and don't have to look up stats) what we are going to do with the Center position. lots of money tied up into a "weakness" (nothing against Steve except he is playing out of position)

A lot of teams run forms of zone blocking, and they're not ranked 8th against the run. You still have to have the personel with some semblance of talent to implement any scheme.

Way to spin the data. If it's good, it's in spite of our players and if it's bad, it's because of the players.

Maybe the line is as good as the run blocking shows and the pass blocking scheme sucked.


I don't believe either of these extremes, by the way.

Not every team has DD (who is VERY underrated), and some forms of zone blocking are more effective than others. For example, Denver's scheme manages to produce 1,000 yard rushers out of nowhere, yet none of these other zone blocking teams can claim the same achievement. I'm not saying every lineman on the team is garbage, but they just don't work.

[GoBlue]

I dunno how those guys calculated all that but the results make sense to me. Our linemen are below average talent, especially in terms of their athleticism. We can run block with a good scheme (zone blocking) and average ability, but when you ask our linemen the match athleticism with oncoming blitzers forget it. That why we give up so many sacks and why our pass blocking stinks.

Has anyone come up with the formula on how to find a lineman in the draft that can move us up into the upper half of the league?

And pocket presence by the QB.

The Texans supposedly ranked 4th in the NFL in the Adjusted Line Yards MID/GUARD category. From left to right:

Left End - 4.16 ALY (17th)
Left Tackle - 4.14 ALY (22nd)
Mid/Guard - 4.62 ALY (4th)
Right Tackle - 3.75 ALY (23rd)
Right End - 4.35 ALY (12th)

I think the numbers come from the nature of the zone blocking scheme rather that the proficiency of the blocking by the guards and the center. Many Texan rushes start off tackle but are cut back inside. Is the success the result of McKinney dominating or the tackles learning how to clean up the backside of a run? It's interesting that the #1 ranked offensive line in the Mid/Guard ALY category isDenver, another zone blocking team.

Does are rotation seem a little off to anyone, or is it just me?

I thought about throwing that one in there, too, but it seemed like a Carr dig at the time.

I was timing our pocket at the games last year, and the first half of the season was just pathetic. Maybe a second or so before someone made it through the line. The second half of the season was better after they moved Pitts. DC got maybe 2 seconds on a good pocket, and yeah, there were times when he made something of it, and other times where he threw bad passes or ran too quickly (and usually took a sack).

However, the pocket was never truly consistent during a full game all season. And I don't blame it all on the line, because there were many times when the backs just failed to pick up blitzes, or worse, they picked them up but just had no ability to stop them.
