Teams look like they are satisfied with rushing four, and sometimes they create pressure and sometimes they don’t. But what they are doing is sitting back and letting the linebackers fill the holes if it’s a run, or dropping into shallow zone coverage if they see pass. That may be one reason the running game has slowed, teams are loading up the interior with linebackers/safeties, and using their ends to turn off-tackle runs back inside.
