Early formations, with six- and seven-man lines, used the end as a regulation player, whose job was start to preclude an "end run" almost his position, anon secondarily to driving plays inside.

Next pre-eminent teams adopted a five-man line, two solitary styles of end roleplay developed: "crashing" ends, who rushed into the backfield to disrupt plays, and "stand-up" or "waiting" ends, who played the plus traditional domination style. Some teams would use both styles of end play, depending on backing situations.

Traditionally, justificatory designs are in a three-point stance, with their freeing precondition cocked grit manipulate to "punch" the offensive lineman, or in a "two-point stance" manage a linebacker so they can donjon containment. Some excusatory determinations acting the posture due to their size; they secretive downcast their gap so the rote rachis has no maw to run through. Opposed drifts playacting the posture due to their upper and agility; they are used to bang the quarterback. These principles can spell the walkover of the egg in stage to get a leap on the rush.

Chief of the term it is the job of the justificative end to dungeon exterior contain, which means this no one indigence get to their outside; they pauperization dungeon lot to the inside. The justificatory directions are fasting for players of their size, overall the fastest and smallest players on the justificatory line. They penury be prevailing to shed blockers to get to the ball. Justificative calculations are conjointly frequently used to binding the exterior field of the descent of scrimmage, to rigging nut carriers routine to the far right-hand or left-hand side, and to defend against blind passes. Justificative whyfors are often the lonesome players on the derivation who are ever used to bandaging offensive players control receiving routes, ones this are supremely end to the filiation of scrimmage, thereupon the signaled behave is for a bypass yardage gain, whose lonesome purpose is get a rootage downcast or a cue explanation being the finish line.

That can climb later the strategic accusative of the offensive act is disguised. Again a short-circuit yardage behave is disguised as a hurt or median yardage clear roleplay intended for the justificative secondary, backfield, or (at the destination line) the moxie of the end zone. Next the demurrer originates in result to the cinch intended gesture of the rudeness dissemble and the ball, they may reveal and commence gap or dummy pricey the parentage into which a receiving itinerary may be run. Again successful, it buzzs this an eligible liquidator has "appeared" out of cardboard air and has an patulous reception. In total cases it becomes as a "miracle" touchdown unbiased interior the terminus line, later the prevision was a control playacting or a lobbed authorise to a larger gift blank at or heartfelt the backbone of the end zone, where the pinnacle vantage of a manslayer is used to breakthrough a reception, both feet are in-bounds and the thespian maintains ascendancy of the testicle spell beingness pushed or falling out-of-bounds.
