It’s what happens when a clown with a theory comes in, guts the concept of real LBs replaces them with undersized personnel, and then runs a 3 man front . Then moves to 4 man front because they get hammered and can’t stop the rush, but fails to realize you still need LBs with the power and size to shed blockers and fill. But oops there are none around, because Crocker was recruiting off the track instead of the football field. They have the wrong personnel by choice. Catastrophic screw up. Speed without football skills and/or size and power for the position means getting crushed.
