Let's take a look at his profile via cbssports.com:
STRENGTHS: Certainly looks the part of a first round pick, boasting broad shoulders, long arms and a trim middle reminiscent of an NBA power forward. Offers good initial quickness off the snap, as well as straight-line speed to close quickly on the ball-carrier. Martin's best attribute is his strength at the point of attack. He gets a strong initial jolt to his opponent, quickly locking out to survey the action and showing the strength to rip himself free and pursue or stay home, as needed. While not particularly fluid, Martin's length and strength aid him as a tackler, as he's able to grab hold of the ball-carrier and throw him to the ground. Possesses the frame to handle moving inside on obvious passing downs, using his burst to split gaps.
WEAKNESSES: While possessing good initial quickness, he isn't explosive off the ball and is stiff when attempting to turn the corner or when changing directions. This inflexibility allows mobile quarterbacks and other alert ball-carriers to elude Martin in the open field. Does not use his length well to knock down passes at the line of scrimmage, tipping only three passes in 2013 (the same number in 2012)… Broke out with a spectacular senior campaign (including a safety in the Belk Bowl win over Cincinnati) to prompt questions as to where was this consistency throughout his career
COMPARES TO: Justin Tuck, New York Giants -The team that selects Martin hopes the UNC standout will show the same dedication towards improvement that Tuck has since earning a third round pick out of Notre Dame in 2005. Tuck has developed into a fine pass rusher for the Giants but his game remains reliant on his length and strength at the point of attack.
