Last week, we sat out to measure the statistical improvement of the Kansas City Chiefs offensive line. We nailed down some key stat areas we wanted to track throughout the season and I've plugged those numbers in the table after the jump.

One stat I've added is stuffs, which is when a running back is tackled at or behind the line of scrimmage. I think that's another good one to measure the o-line on. I appreciate the suggestions for other stats to track in that previous thread. I decided to stick with the stats that were fairly simple to track and frankly, not that much work to track either.

Before that, here are the rushing stats for the Chiefs yesterday:

Cassel's rushing yards were a huge and pleasant surprise. On the first play of the game, Cassel threw a block 6-7 yards down the field in aid of Quinten Lawrence's run. You knew it was on from there. Cassel had 34 yards rushing and one first down to show for it.

Larry Johnson was moving the chains and looking like a #1 running back again. Dantrell Savage provided a nice spark a couple of times.

All in all, it was a great rushing day for the Chiefs. Gives me a lot of hope for the future.

After the jump, I've got our offensive line stats. Let us know what you think.

If you want a little more background on the run defenses we've played against, the Ravens finished 2008 ranked third overall in the NFL in run defense and the Raiders ranked one spot below the Chiefs, at #30.

With Richard Seymour, the Raiders are definitely improved but still a weak opponent on the defensive line IMO.

The most disturbing change from last week to this week is penalties. The Chiefs had nine total and six of them came on the offensive line. Mike Goff, Rudy Niswanger and Nduke each had a penalty. LT Branden Albert had three penalties himself, two false starts and one holding penalty.

So do you think the o-line is improving? Or are these stats a case of playing a strong then a weak opponent?
