A "dive" (or "plunge") is a type of play in American football in which the ball carrier (usually a fullback or a halfback) attempts to rush through one of the gaps immediately to the left or right of center, denoted as the A gap. It may be run with or without a lead blocker, though when run with a lead blocker it may be called a "lead dive". It is often, though not always, used in short-yardage situations, specifically at the goal line. This play is used with fullbacks or larger, stronger running backs less prone to fumbling because this play values strength over speed. It is distinct from both an end run and an off-tackle run.
