Previously, I took a look at the five sacks the San Francisco 49ers defense managed to get against the Seattle Seahawks. It was a fun time, watching Russell Wilson run for his life, ultimately fail and get sacked time and time again. Aaron Lynch had a great game, and I like what I saw from Quinton Dial. But all this time I knew things were going to get a whole lot worse.

Ah yes, I still have to look at the sacks allowed by San Francisco's offensive line, the only one that can really compete with Seattle's in a battle of sheer incompetence. These offensive lines are truly terrible, and it shouldn't surprise you that I have six sacks to look at today. Six times that Colin Kaepernick was brought down before even attempting a pass.

What's more is the majority of these sacks were so quick that Kaepernick never had time to even think about throwing. He makes his mistakes -- you can always count on him to do that -- but really, the offensive line can be blamed for many of his issues against the Seahawks on Thursday. This was not a fun article to write.

Let's get to it.

(15:00 of 2nd Q) 1st and 10 from SF 38: Kaepernick sacked at SF 33 for -5 yards (M. Bennett)

I captures some video of the coaches' film and was going to make some gifs for that but ultimately, I didn't see much to actually lend value to these plays. This sack, the first one allowed by the 49ers, was actually the longest play of the bunch and there wasn't much to look at in the secondary. You'll see a little coaches' film in this article but most of them are the primary gifs as opposed to supplemental.

The protection is kind of OK in this play above, at least at first. Erik Pears isn't really sure who to block and that complicates things with the initial pressure. But left tackle Joe Staley is the one who makes the most egregious mistake on this play. He works a double with Vance McDonald briefly and then gets completely, utterly lost. He has no idea where to go and his totally absent any kind of hustle. Sack.

(2:36 of 2nd Q) 1st and 10 from SF 21: Kaepernick sacked at SF 17 for -4 yards (Cliff Avril, Michael Bennett)

The right side of the line plays particularly poorly here, though you can guess who the main culprit is: Jordan Devey. He barely touches his guy and he blows past him, making Kaepernick step up into the left side of his line, which is doing its job properly. Heck, you can see Kaepernick run into Alex Boone, who thinks the run is now happening so he starts to go up and block more guys. But after Devey forced Kaepernick to step up, Pears loses his guy and Kaepernick is brought down.

(2:01 of 2nd Q) 2nd and 14 from SF 17: Kaepernick sacked at SF 13 for -4 yards (Michael Bennett)

This was such a weird play. The entire 49ers offensive line shifts to the left side like they're blocking for a screen. They're moving to sell the fake, of course, but they move a whole lot for a fake. They really get out there and Kaepernick has literally nobody blocking guys on the right side of the line. Both Pears and Devey go to block a guy who wants nothing to do with them while the other guy flips right around Vernon Davis to send Kaepernick into the waiting arms of Michael Bennett.

(:43 of 2nd Q) 1st and 10 from SF 20: Kaepernick sacked at SF 6 for -14 yards (Cliff Avril)

Who adequately blocked their man on this play? Boone and Marcus Martin did fine, everybody else ... not really. Staley struggles with his man, Devey blocks nobody, as is his custom and Pears gets peat on the outside. Devey tries to assist Pears but it looks like, if anything, he sort of helps Cliff Avril get to Kaepernick. The receiver routes did not develop quickly enough.

(9:14 of 4th Q) 1st and 10 from SF 23: Kaepernick sacked at SF 16 for -7 yards (Michael Bennett)

Devey does a masterful job of being Devey on this play. Fullback Bruce Miller makes a real solid block on the linebacker as Devey soars past him, expertly directing Bennett into Kaepernick. I'm going to assume Devey got confused about the job description and just assumed he was supposed to help the guys with the birds on their uniforms get after that guy who keeps yelling at them. Either way, it's clear he wants to get Kaepernick sacked here and he does just a bang-up job on it. I'd give him an A+ for achieving his prime directive.

(8:32 of 4th Q) 2nd and 17 from SF 16: Kaepernick sacked at SF 7 for -9 yards (David King, Brandon Mebane)

Despite clearly holding on to his man, despite making as good an effort as I've ever seen Devey make to block a guy, despite Boone and Pears both being unable to stop their guy from getting to Kaepernick first, somehow Devey's man is still the one to actually sack Kaepernick on this play.

Bravo, Devey. Just a wonderful performance.
