Coaches Film Analysis: 2019 Season

jd, in your video you said this play was to look like outside zone. I see it as inside zone blocking all the way (split zone). The reason I ask is because when I was tallying the run plays for the 49ers, I saw them run split zone a few times and I classified them as inside zone runs.
I feel the 49ers had a hunch what was coming on this play. I think the 49ers knew MIN was going to block inside zone left, so they slant Buckner weakside. The left guard steps one way, Buckner slants the other, he's in the backfield.

Even though they pulled a guard, I see this as inside zone (variation of split zone) due to everyone not named Person stepping in unison towards the playside. Person pulling caused some misdirection. There were little wrinkles here and there in 49ers run game that really messed with the LBs keys.

Here's a play that shows the 49ers knew what kind of presnap checks MIN makes, and used motion to allow Bourne to "block" two defenders.
This is how the 49ers first get aligned. There's 8 in the box.


Bourne motions across the formation and MIN pulls a safety out of the box. I don't know what MIN's original call was, but they are now in Quarters. Quarters safeties play with less depth than Cover2 safeties and are asked to come up in run support. Some consider Quarters as having 9 in the box, with the two safeties being considered in the box, but it's not quite the same as being within 5 yards of the line of scrimmage.


There's now 7 in the box. Bourne peels back across the formation.


When Bourne looks like an option to get a swing screen, it pulls another LB away from the box. Now there's 6 in the box. All that fancy presnap motion just to run a typical Power play. But now with 6 in the box as Bourne is able to remove two defenders simply through motioning.

Kyle Shanahan the Grandmaster of football chess

Took away 2 defenders with 1 motion. Nice breakdown thl

Olin Kreutz, a 14 year NFL veteran Center, is also puzzled what this blocking scheme is lol. Creative stuff. Wish the run popped for more than 4 yards. If only McG didn't over run that LB.

I wonder if it was supposed to be 4. It looks like glinch is firing for the DE, i wonder if the TE was supposed go behind and attack the backer.

That will also allow for the TE to get behind the backer on a PA.

JD, I remember in your breakdown of the packers you correctly identified it was their LB's as their weakness. Is this mainly in pass coverage or run or both? Do you think we use the same formula attacking them as week 12 or do you think we rely a little more on the run since I don't remember us running much week 12 and I know our OL wasn't as healthy as it is now

Considering the past history of McGlinchey and his mental screw ups including not being set before Hunter ran past him I would assume our RT blew it.

Yeah the other way that could explain it not being a mistake. If he is there for when the TE lets the end go and run to the flat as a checkdown.

I can not wait to see the play that is setting up.

The split zone looks to attack inside the tackle whereas the outside counter usually goes outside the tackle.

That's a power play with no lead blocker. Saleh calls it, "crunch"

B gap? I believe on split zone, the RB has the freedom to use the kickout block (sift) as a cutback option, just outside the tackle, inside of the sift block.

Crap. I guess that's one incorrect play I tallied.

As far as I've understood, the counter, the tackle will collapse down and you'll have a kick out on the EMLOS by either a TE or FB.
With the split zone, the cutback will go up A or B gap and the tackle will look to get to the 2nd level but the RB has freedom to cut back or not.

I usually look for where the cutback attacks harder, on the split zones, usually it's right down the middle of the field and counters you'll see the running back cut outside.

I think we will attack them, but not necessarily the same way. Kind of like we did with seattle
Some stuff was the same, some new wrinkles.

GB just isnt as strong down the middle. They don't eat up a lot if double teams with their DT's and their LB's are a little slow, a little small and aren't world changers.

They have a lot of talent outside but that was what looked like the path of least resistance before the game.

You could also call it a trap play, but it looks like Kittle doesn't get to the end level. It would be a DE trap
