Position on the defense, specifically d-line. Usually really big, at or above 6'2" and 270 lbs. Don't get much
recognition unless they are a superstar, like if they get a lot of sacks or pass deflections, or picks, or very rarely, pick 6's. They are
responsible for
plugging up the holes so running backs and quarterbacks can't rush to gain yardage. Often mistaken for an easy job. They handle the grunt work so the linebackers, db's, coaches, and owner look good. Numbered usually from 60 to 79 or 90 to 99.
