Perhaps the biggest reason for Cox enjoying so much more fanfare is the fact that he's a more talented pass rusher than Boyd, whose thick lower body helped make him the more consistent run defender, especially when it came to handling double-teams.
He enjoyed quite the breakout campaign last year (51 tackles, eight tackles for loss, 4.5 sacks) after registering "only" 24 stops (7.5 TFL, 2.5 sacks) in 2010 and 17 tackles in three starts (played in all 12 games) as a true freshman in 2009 and thus must prove it wasn't a fluke, but make no mistake, Boyd has the talent to warrant top 64 consideration.
Weaknesses: Plays too light at times and struggles with his base strength. Offers a limited array of pass rush moves and is undeveloped as a pass rusher, rarely getting consistent pressure on the pocket. Allows his pads to rise off the snap and needs to improve his anticipation off the ball. Doesn't always finish and needs to do a better job breaking down on the move. Lacks the natural power to do much after his initial move doesn't work. Sometimes has the bad habit of playing to the level of his competition.
