In gridiron football, an end run is a running play in which the player carrying the ball tries to avoid being tackled by running outside the end (or flank) of the offensive line.[1] It is distinct from a dive, which is a run "up the middle", or an off-tackle run, which is a run through the inside gap created by the offensive tackle. Most option offenses are based on the end run.[2] For example, in , a character states: "You need to take it to the Captain, fine – through me. You do an end run around me again, I'll snap you back so hard you'll think you're a first-year cadet again."[3]
When faced with an opposing team using the end run, one requires three things to stop it: outside containment (from say a cornerback), defense of the cutback (from say a defensive end), and a safety (to defend the halfback pass).[2] [4]
