Biography: Two-year starter awarded all-conference honors as a senior with totals of 22 tackles/3.5 tackles for loss/1 sack. Junior numbers included 31/3.5/1. Underwent knee surgery after the season and may not be ready to start the 2012 NFL campaign.

Positives: Tough, hardworking interior lineman who does the little things well. Plays with good pad level, gets leverage on opponents and clogs the middle of the field. Works hard, chases the action and is a load in the middle of the line. Displays quickness off the snap, gets double-teamed by opponents and is tough to move off the point. Shows good power in his lower body and effectively uses his hands to protect himself.

Negatives: More of a space eater in the middle of the line than a defender who makes plays. Possesses marginal pass rushing skills. Coming off a major knee injury.

Analysis: Chapman was an important cog in Alabama's defense who allowed his teammates to make plays on the ball. He has the style and body type to line up at nose tackle in the NFL and could eventually develop into a starter once he's back to health and again on top of his game.

Projection: 5th
