Here is the scouting report on Martin from CBS Sports:
STRENGTHS: Only a third-year collegiate player but already boasts the frame of an NFL interior lineman, possessing the naturally thick build conducive to playing in the trenches. Good quickness off the snap, showing the ability to get to the second level as well as seal defenders to create running lanes.
Possesses good core flexibility and natural knee bend to help him anchor against bull rushes. Slides well laterally to mirror pass rushers and keeps his head on a swivel to help teammates.
Plays with some nastiness. Plays to the whistle and isn’t opposed to getting an extra shot in as the whistle blows. A good athlete whose flaws are coachable, suggesting that his best football is still ahead of him.
WEAKNESSES: Only has one year of starting experience at center and is likely to remain at this position in the NFL due to his less than ideal height. Plays very low, which gives him a natural leverage advantage but also makes him prone to effective swim moves from taller defenders. Relies on his punch too much, over-extending and getting himself off-balance.
Spends too much time on the ground because he attempts to knock defenders over rather than simply mirroring them or working to sustain his blocks. Can be a step late in reacting to surprise blitzes. Good quickness to the second level but doesn’t redirect well.
