McCarthy has been a very productive defender, using initial quickness and twitch to beat bigger blockers for sacks. However, he walks around on spindly legs and doesn't have the overall mass to set an NFL edge. The twitch, hand strength and big closing burst should all play in his favor if he proves he has enough instincts to play off-ball linebacker at the next level. He might be worth stashing on a practice squad, as his traits and playmaking potential have merit.
