Biography: Three-year starter who finished his senior season with 41/6/4 after 54/1.5/2.5 as a junior.

Positives: Hard-working defensive lineman who makes a lot of plays with hustle. Bends his knees, quickly changes direction, and gets after the action. Fluid moving laterally, plays with good balance, and actively uses his hands to protect himself. Fast off the edge, rarely off his feet, and plays with good balance.

Negatives: Must improve his overall body strength. Lacks bulk and struggles against large blockers. Average speed in pursuit.

Analysis: Unrein is a competitive college prospect who could be used in a conventional system or as a two-gap end at the next level. He lacks the measurables to be anything other than a backup but possesses all the intangibles to make an NFL roster.

Projection: FA
