Not sure if worthy here.

This was always my thing. It usually never works. QBs generally resort back to who they are when bullets start flying. Easy to "fix it" when that's what you're purposely working on. Live bullets last thing you're thinking about is footwork

good stuff. Thank you

A five man defensive front is wider to defend the edges but that means the second layer of run defense, the LBs, are thinner. Th 49ers will combat this 5 man front by essentially adding gaps to the playside. This is done by pulling OGs, TEs, FBs to help bust through the thin second layer of defense. When an offense pulls a linemen to the playside, they are basically adding gaps since a blocker is a gap. A fullback is a moving gap that can be used wherever, which is why Kyle likes a fullback to make his run game go.

This is the first run play vs SEA.


This is a Power play with Juice kicking out and Brunskill lead blocking through the hole. +5.

-----------------
This is the 49ers second rushing play from the SEA game. Familiar 5 man front.


This looks like a split zone run (inside zone concept) but the 49ers bring two blockers to the playside with a counter step from Sermon to help sell that the play is going left when it is actually going to the right. The key block is Juice with Kittle leading.

---------------------
This is the 15 yard run, longest from scrimmage in this game.


Another split zone (inside zone) play. With Lance being a run threat, Juice can disregard the edge defender and allow Lance to "block" him.
With defenses using 5 man fronts to contain the edges, the 49ers are adjusting by being more of a straight ahead running team using gap blocking runs and inside zone. Pulling guards, adding a FB/TE to the point of attack to punish the thin second level of defenders.

Continuation of how the league trend in defenses is shifting away from single high (Seattle Cover 3) to two high safeties. I remember Kyle speaking about why he called inside zone running plays versus when he called outside zone plays. This is from 2017.

Reporter question: Speaking of the good plays, it seemed like those runs, in particular, were between the tackles and the outside zone runs were less successful. What were the break downs on those outside zone runs and have you considered de-emphasizing that play at all?

Kyle: "No, not at all. Every inside zone run was versus a two-shell defense when they're one man short. So, we happened to get in the right play versus a two-safety defense when they are outnumbered. The eight-man fronts, if you get into those tight ones and you're outnumbered times two, if you do an outside zone, at least they have to honor the keeper, so you have the numbers. It depends on what type of front you're going against."
---------------------

In this thread there were examples of what defenses are doing to defend the outside zone - using a five man fronts. Combine this with how defenses around the league are moving towards two high safeties (particularly Quarters) and we can understand what Kyle is trying to do when he drafted Banks, Sermon, and what he will be doing with Lance, which is adding zone read elements to the run game (inside zone blocking). Five man fronts + two high safeties = more inside zone and gap runs.

A lot more Bear fronts recently too

What's shown below doesn't happen all the time, of course, but that GB is willing to do this to stop outside zone is telling of what defenses are doing. I would think something like this would cause the pass rush to suffer, selling out to stop outside zone. But this is it, five man Bear front with a two safety shell. #91 aligned way outside the TE to prevent getting sealed to the inside.

Good read about Seattle's transition to bear front to start the season and possible switch back

Through five weeks, the #Seahawks reinvented their scheme with bear fronts as the new base defense.

But against the Steelers, Pete Carroll and Ken Norton Jr. reverted back to their roots with promising results.@mattyfbrown and I break it down:https://t.co/PU69QFUBEY

Good read. What do you think of this 'gap and a half' technique going around? Is it something the 49ers should look into, or just stay with the one-gap wide9? Against teams that use zone read to play 11v11, using '1.5 gappers' would give the LBs more freedom and less run fit responsibility so they aren't susceptible to playaction. Interesting that's why SEA went with Bear fronts. Apparently, Armstead was doing '1.5 gap' at Oregon.
(from article: The advantages of bear for Seattle were how it enabled the defense to play under center play action bootlegs, allowing the second level defenders to slow play their run fit versus wide zone action due to the lack of a B gap bubble.)
