The Bear set inside the 46 formation is a defensive alignment, not an offensive personnel grouping, and that distinction matters for how you deploy it. Where the standard 46 sets stack bodies in the box with wide edge alignment, Bear walks the interior defenders down over both guards and the center (the NT tag tells you the nose is anchored right over the ball), leaving zero free interior gaps for the offense to double team into. That means five defenders are covering the five offensive linemen man to man before the snap, which is the entire premise of the Bear front: every offensive lineman has a body on him, so nobody is climbing to the second level and your linebackers play free.
Bring this set out on second and short or third and one when the offense is in heavy personnel, because interior gaps are sealed and the only place to go is outside where you can rally.
Show the Bear front, then shade coverage inside and pinch the linebackers to bait an outside run, then user the free safety over the top and fill the alley yourself.
Alternate Cover 3 and Cover 1 from the identical alignment on back to back downs so the quarterback cannot key the shell, and manually user the middle linebacker to take away the seam on the Cover 3 look.
Save Engage Eight and 46 Mid Blitz for obvious pass situations when the offense is backed up, and only send it when the opponent has shown a slow developing route concept on film.
Use Slant Weak to attack a run heavy tendency to the weak side, and check out of the set entirely if you see three or more receivers to one side, since your linebackers will get isolated in space.
