BIOGRAPHY: Three-year starter who totaled seven tackles in three games last season, after being sidelined with a torn bicep. Awarded All-Conference honors as a junior after totaling 39/7.5/2.5.
POSITIVES: Tough, athletic defender who plays with top effort. Gets off the snap with a quick first step, is fluid changing direction and slides off blocks to make the play. Bends his knees, gets leverage on opponents and is rarely off his feet.
NEGATIVES: Gets wired in blocks and is slow to shed. Makes most of his plays up the open field in a small area.
ANALYSIS: A hard-working lineman with a lot of physical skill, Harrell could be one of the most underrated players in this draft. His injury last season will decrease his final grade, yet he offers starting possibilities as either a two-gap lineman or as a conventional tackle.
