Parade All-American out of Seattle. Following a 2009 redshirt season, he saw his first college action in 2010 as a reserve defensive lineman and had 18 tackles, three tackles for loss and no sacks with one pass batted in 12 games. Appeared in 13 games in 2011, starting twice at defensive end in December, and contributed 19 tackles, six tackles for loss and two sacks. Played in all 12 games (11 starts) in 2012 and recorded 48 tackles, 8.5 tackles for loss and three sacks with one pass batted. Was the listed starter in nine games at defensive end and two games at defensive tackle. Started all 12 games at nose tackle in 2013 and had 40 tackles, nine tackles for loss and 2.5 sacks with one pass batted. Recorded Cal's first safety since 2008 (against Washington State). Team captain. At the combine, hurt his right knee running the 40-yard dash and did not work out.
Outstanding arm and body length and overall size. Is not easily moved off a spot. Can anchor vs. the double team and clog lanes. Very tough and durable. Plays through injuries. Versatile and has experience lining up anywhere along a "30" front.
Not an accomplished pass rusher -- hand use is unrefined and displays minimal acceleration and closing burst. Has to figure out how to work half a blocker. Tends to rise straight up out of his stance and stays blocked too long. Limited playing range. Lacks urgency. Has a hearing impairment in one ear.
A very big, strong, two-gapping plugger ideally suited to stack the corner of an odd front. Will make a living digging his feet in the dirt and defending the run. Has enough athletic ability and movement skill to be disruptive inside, and versatility is a plus.
