Rex Ryan's scheme gives everybody a chance to rush the quarterback. Harris does a decent job at this, although one cannot expect him to break Michael Strahan's record soon. He blitzes with a lot of aggression. Even when he gets engaged, he keeps fighting through, pushing his blocker back. I seldom see Harris allow a man blocking him to be able to help on another guy.
Harris does not have many moves, but he is not a pass rusher by trade. Overall, he is a net plus as a blitzer. He is near the top end in the league in categories like quarterback pressures and hits at his position. He does get called upon more than most guys, but he does get the job done his fair share of times.
