The main difference between a 3-4 defense and a 3-8 defense in football is the number of defensive linemen and linebackers on the field. In a 3-4 defense, there are 3 defensive linemen and 4 linebackers, while in a 3-8 defense, there are 3 defensive linemen and 8 linebackers. This affects the defensive strategy and coverage schemes used by the team.
A 4-3 defense is a defensive front that consists of 4 defensive linemen (typically two tackles and two ends) and 3 linebackers.
Jim Herrmann was defensive coordinator and linebackers coach for the 1997 Wolverines.
Playing in the box refers to the players whose job it is to stop the run. The Box is usually a combination of 7 defensive linemen and linebackers. They are usually arranged in either a 4-3, 3-4 or 5-2 where the format reads lineman-linebackers. You may sometimes here a team as having 8 (or more) in the box. This occurs when a team brings up defensive backs even with or in front of the linebackers in obvious running situations.
A defensive player who lines up behind the defensive linemen and in front of the defensive backfield. The linebackers are a team's second line of defense.
The answer is usually 3 or 4 depending on whether the team plays a 3-4 defense (3 defensive linemen and 4 linebackers) or a 4-3 defense (4 defensive linemen and 3 linebackers). Occasionally teams will line up with 2 or 5 linemen, but this is very rare.
In 1984, the NFL allowed defensive linemen and linebackers to wear jersey numbers in the 90-99 range, since more teams were making use of the 3-4 defense and thus were quickly exhausting numbers for linebackers, who previously were only allowed to wear numbers in the 50-59 range. Since 2010, defensive linemen are allowed to wear numbers 50-59; this is in part because of the interchangeability of linebackers and defensive ends (a defensive end in a 4-3 defense would be an outside linebacker in a 3-4).
That sport is the game of football. There is a nose tackle, 2 defensive ends (rushers),2 cornerbacks, 2 safeties,and 3 linebackers. (From left to right) Sam, Mike, and Will.
A nickel back refers to a position on defense in American Football when a team adds a fifth cornerback, subbing out either a down lineman or linebacker. This type of defensive substitution is typically run in obvious passing downs. When a team runs this type of formation it is usually called the "Nickel D". If you have a base 3-4 base defense, you would have three down linemen (D. Tackle, Nose Tackle, D. Tackle) and four linebackers (ROLB, RILB, LILB, LOLB), two corners and two safeties. In a nickel D, the 3/4 defense typically subs out a line backer so the defensive front would be 3/3/5, three linemen, 3 linebackers, 5 defensive backs. In a 4-3 base defense, you would have four down linemen (D-End, D-Tackle, D-Tackle, D-End) and three linebackers (LOLB, MLB, LOLB), two corners and two safeties. In a "Nickel D", the 4-3 defense could sub either a lineman or a linebacker. If you sub out a line backer, the defensive front would be 4/2/5, four linemen, 2 linebackers, 5 defensive backs. If the team were to sub out a lineman the defensive front would be 3/3/5, three linemen, 3 linebackers and 5 defensive backs.
Middle Linebackers are usually positioned behind defensive tackles and/or in-between the defensive linemen and the defensive backs (Cornerback, Strong Safety, Weak Safety.}Middle Linebacker
the 4-3 simply means there are 4 defensive tackles and 3 linebackers in that formation
they line up behind the defensive line thats why they are called line backers
