Another term generally reserved for defensive front seven players. A "high-motor" defensive lineman can penetrate the offensive line to rush the QB and make plays behind the line of scrimmage, but he can also chase a ball carrier downfield. High-motor guys must have superior endurance to stay on the field for long stretches as opposed to being subbed out as part of a rotation.
A "high-motor" LB has the lateral range to make plays from sideline to sideline, and he is an every-down player who can rush the passer and stop the run.
