Preseason Chargers vs 49ers: Breaking Down The O-Line Tape - Preseason Week 4

The San Diego Chargers lost to the San Fransisco 49ers 20-17 Thursday night. Even though the Chargers lost the game,many of the players that were on the bubble got the opportunity to show their stuff before final cuts.

The starting offensive line came out of the game at 12:04 in the second quarter which gave the fans a good opportunity to check out the next group of blockers like Tyronne Green, Stephen Schilling, and Hutch Eckerson. How did they do?

This week we will cover the O-Line for Bolts from the Blue. We have broken down every play in the first half and have grades and notes for the performances.

Let's take a look at those numbers...

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:

  • There wasn't many power blocks by the offensive lineman this week. The San Francisco 49ers had stout defenders and had their way with the second group of offensive lineman (especially in the pass rush).
  • Hutch Eckerson had the best run blocking power score for the Chargers this week with a +1.
  • Ahmad Brooks #55, a linebackers for the 49ers, proved to be a problem for the first and second units. He was physical and very quick.
  • Brandyn Dombrowski starts off good in the run game but then, just before the first unit comes out, he misses some blocks.
  • Hutch Eckerson and Colin Baxter can both run block well. The only problem is that they are a liability in pass protection. At least they were in the San Francisco game.

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 Notes:

  • At 5:38 in the 1st quarter, Brandyn Dombrowski has a nice cut block in a three step pass protection.
  • The Chargers offensive tackles were having some problems, not big ones, but problems with the 49ers on the edge. Later, when the second group came in, San Fransisco really got to the quarterback. It showed that the 49ers defenders were hard to handle...even for the first group.
  • Kris Dielman has a nice game pass blocking. Never really gets pushed around or out matched on any bull rushes.
  • The first unit does a nice job, overall, in the pass protection area. Some mistakes here and there...but, overall, did well. That's a good sign for Philip Rivers, and the Chargers, going into the regular season.
  • Both Hutch Eckerson and Colin Baxter had very poor games in pass protection. In fact, they had the kind of game in pass protection that sometimes finds players on the cut list. Every passing play Eckerson and Baxter were getting handled by the 49ers defenders.
