TheRanchReport.com's Scouting Report: A shutdown corner with adequate size and outstanding quickness. Has race horse speed, a very smooth compact, explosive hips and the ability to stick his foot in the ground and close to the ball. No wasted movement or extra steps. Underneith close was rare. Impressive play instincts and anticipation. Has the speed to easily stay on top of receivers on deep routes. Inconsistent hands and was just an adequate tackler. Special player. Top round selection.
