In an "end-around play", a wide receiver or split end runs laterally behind the line of scrimmage, takes a handoff from the quarterback, and continues around the opposite end of the line. As a regular part of the playbook, an end-around with a proper lead blocker such as an H-back or fullback can get positive yardage without relying on trickery. Because the defense normally expects the wide receivers to run a downfield pass pattern, an end-around that catches the defenders by surprise can result in a big gain.
