49ers Head Coach Kyle Shanahan Thread

Well, gonna post here under threat of it getting buried. But, it's the most appropriate spot. Finished the first of 2 scouting videos. Part 2 will be released this evening.

Really hope we hit them with that throw back screen the raiders had. With Deebo that's a house call.

he just dropped this YouTube short lol

I just pay close attention to the Chiefs' defense. I think Steve Spagnuolo will send the six players to bring Purdy down and call for an assault on third down. As far as I know, we have five players on our offensive lines. True?!? We will attack if Purdy is able to read the six defending guys. He must act fast to toss a time!

If the Chief defensive line resembled the Ravens defense the previous time around, Kyle Shanahan might have had trouble calling plays. I hope he doesn't give up since he is playing excellent offense and continues to fight. He is capable. When calling plays as the defensive coordinator, Steve Spagnuolo was excellent. I hope Kyle Shanahan pays close attention to the Chiefs defense and uses his intelligence to determine what makes them successful!

Other than Chris Jones, the Chiefs defensive line is pedestrian. The key is to block Chris Jones on passing and run at him with CMC on running downs.

Short passing to Deebo and CMC and George and hope for the YAC as the defensive backfield will be in man to man coverage a lot.

On kyle shannahan; we where a dumpster fire before kyle shannahan and we have been contenders for many years and win or loose this weekend with this coach and team next year well be in it and for as long as he coaches

Karlaftis is also pretty good. He's having a good 2nd year. Onimehu is out. Danna hasn't been bad either, but he's the guy we need to run at, not Chris Jones. Karlaftis also isn't the best run defense either. So punishing their edges should be priority in the run, a lot of outside zone runs.

Awesome article. Thanks for posting. I like the deep dive into why he is using less playaction while still able to manipulate the underneath defenders to generate passing lanes for the middle of the field throws.

Most of all, the point is that his offense is rooted in causing uncertainty, misdirection, and deception - and that be done in many ways.

I think a big part of less play action is simply Kyle got comfortable with Brock's ability to read the coverages faster than Jimmy. This (to me) indicates why the offensive line has gotten bigger. Less play action. It takes an agile OLineman to do a fake run block and get back fast into a pass protection set. If you don't do a lot of run fakes, you don't need as much agility at the OLine positions.

Kyle will still run the wide zone runs, but now he can do the counter gaps and power because of the bigger OLinemen.

But not using playaction actually provides the QB with more time with his eyes on the coverage. Can , it's actually more difficult to know the coverage when the QB has to turn his back and execute the playaction, then turn back around and readjust his eyes to the coverage. One takeaway I got from that article is that CMC's ability to draw attention is why the 49ers are able to use less playaction. And not using playaction on a certain play means Brock is able to look at the coverage his entire dropback.

I agree with you on bigger OLmen allowing to run between the tackles better. When the team drafted Banks with a 2nd rounder, I knew something was up. Then they went further and drafted Sermon and Price, two guys known for running between the tackles in college.

As much as playaction has been reduced, it's still a big part of the Shanahan offense. You get those big explosive plays off that play action.

As for less play action, the main purpose of play action is to widen the passing windows to the WRs. Like you said, if CMC can widen those windows via route running vs play action, then you don't need as much playaction.

As Brock gets more comfortable in this offense, more option routes can be installed to defeat more kinds of coverages. The danger is going *too far* and not having enough of a run game to have a balanced offense.

I don't watch JT OSullivan breakdowns but I've read folks here say that he doesn't like the bumper motion that CMC does, and that JTO doesn't know why it's done. Read the article to find out why and how it allows this year's 49er offense to not require using playaction as much.

JTO doesn't like that motion cause it gives up 5 yards for no reason to our best offensive weapon. He understands that the idea is to get the LBs out of the middle of the field he just doesn't understand why he wouldn't just put him closer to the LoS so CMC or Deebo can get into their route quicker.

My guess is putting CMC five yards behind the LoS is done to draw the zone defender on CMC's side of the formation closer to the LoS. Meaning, if the defender wants to reduce the space between himself and CMC, he needs to step closer to the line of scrimmage, which then opens up more space in the underneath zones. This is, in effect, the same effect as playaction since playaction also causes the defender to step closer to the LoS. I don't think it's about CMC getting into his route quicker. It's about Brock not having to turn around to execute the playaction (there is no playaction), while gaining the benefit of playaction (defender creeps closer to the LoS). The article touches on this.

Interesting. I sided with Kyle whenever JTO complained about it cause genuinely think Kyle's brilliant when it comes to football design. Just wanted to let you know why JTO did not like that motion. He also hates 7 step drops, Kyle's tradition drop back passing game, Deebos effort and seems to be really butt hurt Juice went to Cabo with Kyle. Other than that he loves us he's a big Brock supporter.

Got it. It does look weird, because he's right, why put any route runner 5 yards behind the LoS? It seems counterproductive. The death of the pro set formation (split back backfields) was because offenses wanted the fullback to get into his route sooner (birth of the slot WR). But I think we all know Kyle does things for a reason and whatever the reason is has more pros than cons, in his mind.

@8:20. Kyle talks about it then the video guy breaks down one play to show how the bumper motion affects the defense. You can see how this affects split safety coverage, in this example, I think it's Cover6 (4v3 to one side, 3v2 to the other). Formation-wise, there is a very distinct division split down the middle of the field (4v3, 3v2) and as the play unfolds you can see it. But what that does is create a lot of space in the middle of the field.

The other part, and I think I heard Kyle say this, is that CMC five yards behind the LoS and motioning out creates a conflict for the defense in that they don't know whether to treat it as a single back formation, or empty. And depending on what the defense does in reaction to this, it gives Kyle information to do stuff.

This all makes so much sense. Reducing the space between the defender and CMC would open the middle of the field more. My question is, what happens when the defense motions over with CMC, but chooses to remain back off the LOS? I think every time I've seen this motion, the LB moves up to the LOS. Why not just hang back? What types plays open up with the defender off the LOS?

Solak is always a good read.

makes a ton of sense and now I kinda get why he drafts/signs who he does. Always "evolving" but the philosophy is the same

CMC emptying the middle of the field opens up the Deebo tunnel screens in my opinion. I think tunnel screens are a great blitz beater play.

We hear it all the time in modern football talk: "They're running the Shanahan offense" or "that's an idea from the Shanahan offense."

You know who isn't running the Shanahan offense anymore? Kyle Shanahan.

Now that he's been here for 7 years, longer than any OC stint, and we know he has a big influence on drafting and signings, we get to see his offense's world view. The core principles are to win presnap - this is done via formation and presnap motion/shifts to create leverage advantages. Create uncertainty in the defense by being run/pass neutral via personnel groups and formation. Be physical. That is the Shanahan offense.

How this is all done depends on the landscape of the league defenses. When he became HC of the 49ers, the landscape was the Seattle Cover3, single high, one gap defenses. Since then, the league has shifted to that Fangio style defense with 1.5 gap, split safety pattern match coverages. Kyle has adjusted to this while maintaining his core principles.
