Khalil Mack is a monster.
The reigning NFL Defensive Player of the Year played an instrumental role in the Oakland Raiders' recent 31-30 victory over the Kansas City Chiefs, harassing Alex Smith all night long. Attempting to block Mack one-on-one is a fool's errand. Chiefs offensive tackle Eric Fisher learned that the hard way:
Fisher is a Goliath, measuring in at 6-foot-7, 315 pounds. Mack is 4 inches shorter and 65 pounds lighter, yet he absolutely manhandles Fisher on this play. To do so, he employs a pass-rushing technique known as the "long arm." Mack stabs Fisher with his left hand, fully extending his arm in the process to create separation. That gives him leverage and a chance to drive Fisher backwards into the quarterback. Yet Mack's long arm is so explosively powerful that he doesn't even need to walk Fisher backwards—he simply forklifts him out of the way. The result is a quarterback hurry and an incomplete pass.
A power rush like this is almost akin to a Sled Push. It takes full-body strength and proper body angles to execute it correctly. Unsurprisingly, Mack told Men's Fitness he did "a lot of (sled pushes) this offseason".
