got flagged for a couple holds and totally whiffed on a few blocks and gave up some pressures. It will be good to get Boone back. Same thing with Martin, he played better in the first half, but, nothing to make me get excited for - those two guys do provide some better depth though as they are both better at their positions than Snyder was at either.

Absolutely love the summary but couldn' disagree more with this one. We watch the OL play very closely and WRATH has even provided a detailed analysis for reference. But it's OK to agree to disagree on this one.

ITA. Looney's flag was a phantom call. In fact I recall their being a tweet about it from a reporter observing "the NFL would like to place more emphasis from preventing you from hugging yourself". LOL

Yeah, it was another textbook pull..NN covered that one pretty well. It was hilarious, the commentary on it!

End my day of production at work......

just waiting for the next post

I'm ditching the All22 thread I created.

MODs: Please merge my thread with this one, if possible. I will add to this instead.

Yeah, they ran a cover 3 zone, which is how the vertical stretch works - it streches the zones out - Here's a wonderful reference guide THl put together, http://www.49erswebzone.com/forum/niners/179447-all22-coverages-and-concepts/

I'm confused You are talking like as if the vertical stretch is something what a DEFENSE is using...But then again, I think I'm stupid

summary: Boys ran a zone coverage and we stretched it vertically, right?

Yes sir, the stretch concept is used by the offense to stretch out the defense.



They're in cover 3 zone - 3 deep, 4 underneath



The entire route combo stretches the defense. The post route pulls the middle and deep 3rd zones up, the RB in the flat holds the underneath defender. This causes a huge area to be opened up because the zones are "stretched" out.

Right on guys. This is the SAIL concept done with a Post pattern instead of a Go route. Any vertical route will suffice in clearing the deep 1/3 zone defender away for the two underneath routes to vertically stretch the curl/flat (sideline) defender. The three routes involved are Crabs (Post, clear out) + VD (intermediate Out route) + Miller (short Flat). VD turning this into a wheel route is him being alert and working the vacated area once he saw Kap had extended the play using his legs.

A zone defender that is alert will recognize what is going on and pass off the vertical route over to his teammate, then jump the underneath.

I'll breakdown all the horizontal stretching the 49ers did to attack the underneath zones using the All Curls and Curl/Flat concepts. This game featured some short range ball control passing that we should be excited about. This simply was not seen last season - the frequency in taking the short underneath pass. We know the 49ers can attack the intermediate areas downfield, but they rarely showed a willingness to 'settle' for the short gain as the first read last season. This resulted in the high completion % and the manageable 3rd downs (when the refs were being fair).

Jonnydel, do any teams use linemen getting low in run blocking to better sell play action? If the linemen can blow the DL off the ball anyway, why isnt run blocking used consistently despite run or pass?

they kind of can - or they try. The NFL rulebook states that a lineman cannot go beyond 1 yard past the LOS on a pass play or it is an illegal man downfield. So, if they fire out, they have to be really careful, also, firing out can be very risky, if the D-lineman chuck the O-lineman(like Justin Smith did in my other post) it's not a big deal on a run play where you're the backside lineman because the DT usually has taken himself out of the play, but on a pass play, that means you have a free runner at the QB. Pass pro is really hard if you don't have a square base and set hips. So, if a line slants and a defender isn't where a lineman thinks he will be after the snap and he ends up even 3 1/2 feet off the ball, it's a penalty, or if he's beat it's a sack. So, they will try and sell it as best they can, but good NFL defenders are able to identify those things.

agree 100%. Especially on the plays where Dallas would "sugar" the "A" gaps, CK did a great job off seeing when they backed out and taking advantage of the underneath coverage - mostly to Boldin.

whatever they want to call it now
doesn't matter cause they don't call it on us
Goodell and the nfl trying to hold us down
but they can't stop us no matter who they are

Here's one of those example where CK did a great job in recognition when Dallas showed one thing and came with another. What's so exciting about this is that Dallas is throwing as many exotic and funky looks and changes at him they can and it was like CK didn't even flinch, he kept his head right, recognized the defense and made a good play for positive yards - that's exciting.


Here Dallas shows a heavy pressure look. They have "sugared" the "A" gaps, and have a quarters look in the secondary with a press in the slot. This usually means that they're going to be running a man coverage blitz - but they don't they run a zone blitz.


They end up in a cover 2 zone blitz. They blitz the slot corner, back off the strong side ILB and have 2 deep safeties with 4 underneath coverage with the strong side DE dropping into a "hook to curl" zone coverage. The corner on the 2 receiver side though has to respect the corner route from Boldin, so he has to drop deep in his zone.


The blitz does allow a guy to come as a free runner on a delayed rush, but Crabs is wide open. He's open because you can see how both the corner and safety have to respect Boldin's route.


Crabtree catches the ball for a nice gain and yards after catch. You see CK stood in there and delivered the ball even though he was gonna take a hit on the play.

Here's one example of how Wilhoite needs to get better in his pass drops:



On this play we're going to run a cover 3 zone defense. Bethea is going to rotate over to a the single safety and Reid will come down into the box.



Dallas is going to run a skinny post on from at the bottom, a drag from the TE and an out from the top. They run play action to pull the LB's up to open up a zone in the middle of the field. You see how it pulls Willis, Wilhoite and Ward up a little bit.



Ward and Willis recognize the play action sooner than Wilhoite, who's late in his drop.



You see how much deeper Willis is than Wilhoite by this time and how big of a hole is opened up.



You can see both Ward and Willis get good depth on their drops, but Wilhoite doesn't



When Romo throws the ball, because Wilhoite didn't get good depth on his drop, it's left a hole for Romo to get the ball into. If Wilhoite is as deep as Willis, this play is busted.



He tries to make up for it, but it's too late. 18 yard gain.

Very nice breakdown and highlighting of how important the ILBs are in the 49er passing defense. Because the 49er CBs play off coverage so often, the CBs are in essence, taking away everything vertical. This leaves the CBs vulnerable to inside breaking routes such as slants, and in this case a skinny post.

Bow was great at play recognition. If he was ever very fooled by play action, he would quickly recover to drop back, gain depth, and take away the Curl zone, which is the throwing lane for slants (skinny Post). Nice work showing how Brock relies on those ILBs to help out, and they (Whilhoite) did not provide the help needed on this play. Brock is not at fault for any reason here. His assignment is to play over the top and take away anything vertical.

how do you get these pics ?

This thread is spot on. Good stuff. Kept me busy for an hour. Keep up the good work.

I watch the coaches film from NFL game rewind and pause the play at different points, take a screen shot, then edit the photo's with highlights of what I'm trying to draw attention to as to why certain plays happened the way they did. It's a little time consuming lol but a labor of love
