Weaknesses: Undersized; lacks ideal height and bulk. Not a good fit for schemes that require two-gap ability. Plays with a narrow base and will get overwhelmed by bigger blockers in the phone booth. He struggles to anchor when teams run at him and he really needs to be on the move in order to be successful. Durability has been somewhat of an issue; redshirted in 2003 due to injury that required surgery and missed three games in 2006 (Nebraska, Arizona and Washington State) due to right knee injury that required arthroscopic surgery.
Overall: Ellis arrived at USC in 2003 but received a medical redshirt after suffering a midseason left ankle fracture which required surgery. During his first three seasons (2004-'06) he saw action in 34 games making 86 total tackles, 16 tackles for loss, and nine sacks. Ellis missed some time in 2006 after having arthroscopic knee surgery. Ellis is a one-gap defensive tackle prospect that isn't for everybody but can be effective in the right scheme (see: Colts, Buccaneers, Eagles, etc.). If ranks among the elite prospects at his position and can solidify a spot in Round 1 with a healthy and productive senior season.
