Trap run
In American football, a trap play, or trap run, is a run consisting of a defender on the line of scrimmage getting trap blocked by an offensive lineman or back from the opposite side of the ball. The play is known as a "trap" because the strong side offensive lineman will "block down" on a linebacker, seemingly leaving a defensive lineman unblocked. As the defensive lineman comes through the seemingly open gap/hole, he is "trapped" by the weak side guard who blocks the defensive lineman's blindside. Occasionally, a trap block will come from a tight end. Trap blocks by tight ends are known as "wham" blocks.
Typically, flow will start out one way and the back will receive the ball going away from flow where the trap is taking place.History
