Kansas City Chiefs vs Vikings: Breaking Down The O-Line Film

Week #4

The Kansas City Chiefs pulled off a 22-17 victory over the Minnesota Vikings this past Sunday. The Chiefs go to 1-3 as the Vikings Drop to 0-4.

For the second week in a row, the Chiefs run blocking scores are a little low. No one graded out as having a horrible game...but there wasn't any lineman who really dominated, either. Branden Albert had the best assignments grade at 91% and a +2 power score (which is good).

Let's take a look at the rest of those grades...

Team Run Blocking		Power Blocking		Power Blocking Score		2nd Level Blocks
Did the lineman get the job done or not? These grades are good for understanding value for a team and not necessarily for comparing across teams. A game in the mid 80s to 90% is a decent score.		How often did the offensive lineman dominate the block or how often did he get dominated? These scores are good for comparing across teams and finding the most dominant lineman in the league.		Anything over zero is a good score. The more over zero the more the lineman dominated the defender. Each lineman is scored a minus for being dominated, a zero for a draw, or a plus for dominating the defender.		The number of success over failures for the lineman when blocking linebackers and safeties on the second level. The lineman must be athletic to accomplish a high second level score.

Run Blocking Notes:

A mediocre game for the Chiefs and their run blocking. Asamoah has a few problems with his match-up, and Branden Albert does well.
The Chiefs are pretty good at the 2nd level. What they lack, is the ability to get movement on the offensive line, even in double teams at times.
12:13 in the 1st quarter, both Ryan Lilja and Jon Asamoah pull to the left of the formation on a run play and miss the middle linebacker that scrapes shallow to make the tackle on the running back. Minnesota's linebackers were very good at attacking up field and creating problems on the Chiefs side of the line of scrimmage.
Ryan Lilja gets a nice 2nd level block at 9:49 in the 1st quarter to spring a run by Thomas Jones. 2nd level blocks are critical for big runs and are one of the most difficult blocks for a 300lb lineman to make.
At 9:11 in the 1st, Jon Asamoah shows a good motor to stay with a defender on the 2nd level. It's good to see lineman give extra effort to stay engaged on the 2nd level.
Jon Asamoah and Casey Wiegmann drive their defender about 4 yards down the field at 1:44 in the 1st quarter. Nice to see some Chiefs players driving a defender...need more!
Barry Richardson had a bad game in pass protection this week. But he did do well at the 2nd level. Last year, Richardson's blocking on the 2nd level was poor. This year, to this point, it is looking better.
Jon Asamoah's defender uses a swim move on a running play and quickly gets into the backfield to tackle the running back at 14:18 in the 2nd quarter.

Team Pass Blocking		Passing Power Blocking		Pressures		Combo Help
Did the lineman get the job done or not? These grades are good for understanding value for a team and not necessarily for comparing across teams. A game in the 90% is a good score for pass blocking.		How often did the offensive lineman dominate the block or how often did he get dominated? Each lineman is scored a minus for being dominated, a zero for a draw, or a plus for dominating the block.		How often did the offensive lineman give up pressure on the quarterback? Every once and a while a lineman can do his job but give up pressure on the QB. This stat will help glean more info from the line grades.		How often did the offensive coordinator provide help for a tough defender or a struggling lineman. Yea, two lineman ended up with the same grade...but how much help did either of them get?

Asamoah	90%											-2	1	0	16
Richardson	70%											-8	8	0	9

Pass Blocking Notes:

On the second pass play of the game, Ryan Lilja gets beat for a sack. Lilja has yet to really get it together this year, after his productive season in 2010, and his move to left guard in 2011. His play in run blocking has been down this year and his pass blocking, through 4 weeks of the season, has included a 95%, 87%,82%, and now a 90%. Those two 90s are excellent. But for a lineman that needs to do very well in pass protection because his power run blocking and assignment grades in the run are low...82% and 87% don't seem to be good enough.
Casey Wiegmann and Jon Asamoah work well during a defensive line loop stunt at 10:56 in the 1st quarter. Communication to all the lineman is one of Wiegamann's strengths. That being said, line communication breaks down at 7:46 in the 2nd and it turns into a jail break.
Barry Richardson has a poor game in pass protection this week against Minnesota. At 5:27 in the 2nd quarter, you can see Richardson getting beat, which puts pressure on Matt Cassel. And at 9:07 in the 3rd quarter.
Richardson gets a -8 power blocking score this week (which is poor).
There was a stretch just before half (2:00) that the Chiefs were passing the ball and trying to get some points. Cassel has a lot of time to throw the ball on.
