Zach is very good at reading plays at the line of scrimmage and gets to the ball carrier fast. He's a great tackler who won't over pursue plays. He has a great motor which teams love.
He is small (6'2" 233 lbs) and you wonder if he can play every down. He needs to work on his upper and lower body strength. He'll struggle against the run because of his lack of size but he can come in on spot duty and do some things for a team. His primary role will probably be on Special Teams.
