Biography: Three-year starter awarded All-America and all-Conference honors last season after totals of 52/7/3.5. Junior numbers included 70/20/11.5 after 50/8/2 as a sophomore.

Positives: "Explosive defensive end who constantly makes plays behind the line of scrimmage. Plays with good knee bend and leverage and displays outstanding first-step quickness. Fluid moving around the field, easily changes direction, and gets out to the flanks in pursuit. Rarely off his feet, plays with good balance, and shows speed off the edge and in backside pursuit. Possesses a terrific burst bearing down on the play and gets a lot of momentum going up the field."

Negatives: Struggles getting off blocks once engaged at the point. Handled by a single opponent at times. Coming off a disappointing senior season. Has a shoulder disorder that's been with him most of his life.

Analysis: "Much was expected from Clayborn entering the season as NFL scouts ranked him as one of the best senior prospects in land. However, he did not deliver the desired pass rushing results. Clayborn did improve his play against the run and is starting to develop a complete game. He is not the special defensive lineman some have made him out to be, but he offers starting potential in the NFL and should develop into a dependable three-down player if he's motivated."

Projection: 1-2
