Outside receiver with the size to intimidate smaller corners once the ball is in the air, but they are sure to be right there with him. His ball-tracking and catch instincts make Mack a fun study, but projecting him into the pro game is a challenge. He's a build-up runner with below-average top-end speed and lacks even functional shiftiness underneath to separate. While contested catches will be a concern, the bigger issue could be simply getting off the ball cleanly against NFL press.
Low-cut three-technique with muscular frame and good lean mass. He gets off the ball with good hand quickness into the blocker and plays from a point of leverage but often fails to diagnose the play. A lot of his energy is spent on dealing with the blocker in front of him, so he's not much of a playmaker. His rush is spearheaded by his upfield charge and he occasionally moves a guard around with a bull rush, but he's not a very dynamic athlete as a pass rusher, limiting his potential at the next level.
