Transferred to USC before 2012 season, and exploded for 19.5 tackles for loss, 13 sacks and four passes defensed while playing at defensive end for the Trojans ... Suffered several injuries early in his senior season, and also had hernia surgery in November of 2013 ... Still ended his year with eight tackles for loss and 4.5 sacks ... Played mostly defensive end in college, but is an explosive player with some linebacker experience ... Reads the run very well and will make an opponent pay for mistakes in blocking scheme ... Struggled to stay on the field this past season and injuries are a concern.
