This section looks at their 4-2, 4-3 and bear package. It also takes a look at some 3rd down concepts which includes their load front and mug pressure package.
Fronts
In addition to their nickel 4-2 they have certain packages vs 12 personnel and heavy packages.
vs 12 you will see them play some traditional 4-3 with either cover 3 or 2 with 3 lb's in the game. Below, the DE is the d gap players, sam has c, mike has A gap and the will B gap.
Example #1
Nice job of everyone doing their jobs in the base front vs 12 balanced.
Example #2 vs Seattle.
Movements
One of my favorite run stunts is when they move the DT from a 2i across the centers face and fill the offside LB to the A Gap. Good against all defenses
Bear Package
In addition to their traditional 4-2 and 4-3 fronts vs 12 you will see them be in bear at times and they used it vs the Seahawks in the playoffs.
mike 54 plays front side A and 57 the will plays the c gap on the backside. CB plays the edge if it spills and Bosa 97 is the d gap player.
Another 12 formation, this time 3x1 and they stay in their 4-3 base package. They slide the LB's over because it's 3x1 and they bring the Safety Hufanga 29 down around the ball weak and play 3 weak.
do a nice job on the front side and the lb with the nice run thru
Another example is when the Hawks come out in 21 and run boot. The 49ers go 3 weak and get underneath the deeper route and force the check down on the boot.
You will see some 3rd down coverages. One is they play 2 hole with some of the condensed formations. They take away the windows in the middle of the field. Heres an example of the defense below.
They go double mug which forces the Seahawks to keep their rb in. They then play cover 2. Seahawks run a nice route combo and get the first down.
Load Front
Here's another 3rd down and they run the load front. They run a game with the defensive end and the nose guard. They play 3 weak and get the sack with the excellent coverage down field.
Empty formation. Presnap 2 shell.
post snap, start moving to 3 weak with safety to top of the screen strarting to come down.Another Load Front
Mike goes on the pressure.
They play man free with the LB responsible for the running back playing underneath once the running back blocks.
Here it is, load to the left. with the mike and will mug look. Interesting here because Fred Warner is the 4th de as it's really a 3-3 formation grouping
You can see here #54 Fred Warner is a de on the right. It's 3-3 personnel.
The mike will go 56 to the left a gap with the nose going to the right A gap.
57 drops and has the rb but he stays in and blocks so 57 drops and acts as a rat defender.
