Matt Waldman’s Rookie Scouting Portfolio showcases the elements of an effective stiff-arm, which 2019 NFL Draft prospect Devin Singletary delivers on a Marshall defender. 

The Heisman. The Flipper. The Forearm Shiver. The Jab. The Bolo Punch. The Swipe. The Yank. The Head-Tilter.

There’s a wide variety of effective stiff-arms. Although some are power moves, it’s fundamentally a move that involves gaining superior leverage.

Devin “Motor” Singletary showcases an excellent display of leverage with this stiff-arm on a Marshall defender below. Note the placement under the arm, Singletary’s awareness of his angle of approach relative to the defender’s path, and how the runner uses that information to his advantage.

A good stiff-arm is not only a product of arm and hand placement, but effective use of the legs, knees, hips, and footwork to maximize the yardage after the contact. Singletary’s understanding of leverage and integration of multiple forms of movement into a single process is a good indication of a skilled runner.
