The San Diego Chargers beat the Baltimore Ravens last Monday night, 34-14. The Chargers improve to 7-7 on the season and the Ravens fall to 10-4.
In this weekly article, Pro Football Spotlight will bring you the blocking performances against the recent opponent, as well as some additional data. For example: Did you know Randy McMichael ended his day with a 84% run assignment grade?
Let’s take a look at those blocking grades…
***
| Team Run Blocking | Power Blocking | Power 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:
- Jacob Hester ends his day with a 85% run assignment grade.
- At 11:59 in the 2nd quarter, Jacob Hester has a nice lead block to the right of the formation in which you cuts the defender. You can see him, below. He is just cutting the defender.

- At 10:57 in the 2nd quarter, Randy McMichael has a weak lead block from the fullback position. We would like to see a little more of a collision that jolts the defender so he cannot recover in time to get off the block and make the tackle.
- Kory Sperry ends the day with a 66% run assignment grade. And at 12:25 in the 4th quarter, he doesn’t show a lot of energy on the block. He typically is a blocker that comes in and has a high motor and is tenacious during the block…but not on this play.
| Team Pass Blocking | Passing Power | 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? |
- Pass Blocking
Pass Grade Bar Power Pressures Sacks Combo Grade Score Allowed Allowed Help Gates 98% 
0 0 0 0 McMichael 66% 
-1 1 0 1 Tolbert 98% 0 0 0 3 Mathews 66% 0 1 0 1
Pass Blocking Notes:
- At 11:23 in the 2nd quarter, both Randy McMichael and Ryan Mathews are beat by a defender. You can see them in the pic, below. Although it is a little fuzzy, McMichael had just been thrown aside and the back had to pick up his defender instead of taking the inside rusher…which he should have done. Rivers is sacked on the play.

- McMichael ends the day with a 66% pass assignment grade. Not a great day in pass protection for Randy.
- Antonio Gates is asked to pass block very early in the game. All the other times, he is in a pass route.
- At 4:11 in the 3rd quarter, Ryan Mathews picks up a blitz so Rivers can make a big throw to get the Chargers to a 1st and goal.
