The Bear set in the 46 formation is Madden's classic run-crushing front, built from Base 4-3 personnel with an eight-man box look. The NT lines up directly over the center while the RDT and the opposite tackle cover both guards, taking away the A and B gaps before the snap. The RLE and RRE widen outside the tackles, and a linebacker walks up on each edge. That leaves the Mike stacked in the middle and the strong safety rolled down as the eighth defender. Other 46 sets spread the front more conventionally. The Bear alignment removes double-team opportunities on the interior, so every offensive lineman is covered and every block becomes a one-on-one.
This front attacks the offense rather than reacting to it. Inside zone, duo, power, and counter all struggle because pullers get picked off by covered interior linemen, and the extra box defender fills whatever cutback lane survives. The Bear also creates pass rush mismatches. Stunts and slants from the NT and RDT punish slow guards, while edge pressure from the RLE and RRE forces quarterbacks off their launch point. Slant Weak and Slant Weak 3 shift the line at the snap to shoot gaps and blow up zone blocking schemes.
The tradeoff is coverage. With one deep safety and the strong safety committed to the box, the back end is usually a single high shell. Cover 1 and Gap Press lock corners in press man to challenge receivers at the line. Cover 3 and LB Blitz 3 add a buzz zone element that helps against the quick game. Safety Fire, 46 Mid Blitz, and Engage Eight let you bring pressure from angles the offensive line cannot identify pre-snap, which isolates backs and tight ends in protection.
Call the Bear on short yardage, goal line, and obvious run downs against heavy personnel like 22 or 13, where the covered interior front gives you the biggest edge.
When the offense motions to trips or empty, audible to Cover 3 or LB Blitz 3 rather than staying in Cover 1 to avoid getting isolated on crossers and seams.
Use Slant Weak or Slant Weak 3 against stretch and outside zone teams, and shade the line toward the tight end side so the slant hits the play side gap.
User the deep safety or Mike against play-action heavy opponents. Stepping into the middle hook zone takes away the easiest throw off run fakes.
Mix Safety Fire, 46 Mid Blitz, and Engage Eight with base Cover 3 from the same presnap look so opponents cannot read the blitz, and pair man coverage calls with a spy or contain adjustment against scrambling quarterbacks.
