He can still get quickly to the edge. Honestly that is all I care about at this point - someone who can make the defense run side to side - McKenzie is okay at that but he runs the same play every time for the most part (either the quick pitch or the fake quick pitch). Hunt adds more versatility in that he can run up between the tackles, catch passes out of the backfield etc. But the basic role is the same - move the linebackers side to side to open up the middle of the field a bit.
