Pass Rush
Bosa possesses a variety of pass rushing techniques, but he is at his best when he can use his length and natural power to drive back a blocker. Both of these are your classic bullrushes. The first one is my absolute favorite play by him in all the tape I’ve seen. A “stab-and-grab” where Bosa drives him back using one arm and then grabs the inside arm of the blocker to prevent him from breaking his grip. Just beautiful.
In addition to the bullrush, Bosa uses his hands plus length effectively to deliver a powerful punch while not allowing them to touch his chest plate and get a full grip on him.
One of the things he needs to work on is his speed rush where he seems to be too stiff to dip and rip around offensive lineman. A common tactic they used to neutralize this rush around the edge was to escort him out of the way by widening his angle of pursuit.
Additionally, he showed a swim move a few times, but he leaves himself too open for a shot to the inside arm/stomach area by going too high and exaggerated with the move.
Lastly, he has shown flashes of putting moves together like a bullrush to a spin move, which is definitely good to see, but he still needs to pair them more effectively and more frequently.
He also had a good double-swipe move that is also used by Redskins’ Ryan Kerrigan, which is why some feel they are a pro comparable.
