who runs a 3-4 defense in the nfl
3–4 defense After becoming the predominant defensive alignment in the late 1970s-early 1980s,[1] the 3–4 defense declined in popularity over the next two decades, but experienced a resurgence in the 2000s among both professional and college football teams. As of 2017, NFL teams that regularly incorporate the 3–4 defensive alignment scheme as a base include the Green Bay Packers, Oakland Raiders, Los Angeles Rams, Pittsburgh Steelers, Baltimore Ravens, Arizona Cardinals, Indianapolis Colts, Kansas City Chiefs, New York Jets, Washington Redskins, Denver Broncos, Tennessee Titans, Houston Texans, and the Chicago Bears, who used the 3-4 as their base defense for the first time in 2015.
Lineman (gridiron football) In gridiron football, a lineman is a player who specializes in play at the line of scrimmage. The linemen of the team currently in possession of the ball are the offensive line, while linemen on the opposing team are the defensive line. A number of NFL rules specifically address restrictions and requirements for the offensive line. The defensive line is covered by the same rules that apply to all defensive players and the offensive lineman are supposed to help block the quarterback from getting sacks for a loss or even worse a fumble.[1] Linemen are usually the largest players on the field in both height and weight, since their positions usually require less running and more strength than skill positions.
