In American football, an eight-in-the-box defense is a defensive alignment in which 8 of the 11 defensive players are close to the line of scrimmage. ==Description== The area occupied by defensive linemen and linebackers is often referred to as "the box". The box is usually about 3-5 yards in depth and spans the offensive line in width. Normally five to seven defensive players occupy this area but frequently another player is brought into the box for run support against smashmouth-oriented offensive teams or short yardage situations.〔Kirwan and Siegerman, p 214.〕 The most common occurrence of eight in the box in the NFL involves the strong safety walking down from his position (moving to within) 10-15 yards off the line of scrimmage before the ball is snapped.〔Kirwan and Siegerman, p. 215.〕 From this tightened position he can offer the aforementioned run support as well as jam WRs and TEs, blitz the QB, or provide flat coverage. Due to the superior athleticism of NFL players, it is not uncommon for the box safety to even provide deep coverage after the snap, giving the QB a pre-snap Cover 1 read but effectively transitioning into Cover 2 or another shell post snap. Often, to hold a disguised defense, the safety will not come down until the snap of the ball. While this is not the eight in the box strategy, it gives the same results without showing what your defense is before the snap of the ball.
