Kevin Ellison overview from NFL.com. Overview Steady, no-nonsense strong safety ended his career with 34 starts and earning first-team All-Pac-10 honors after each of the past two seasons. An instinctive defender, Ellison has morphed into a coach on the field for the Trojans. While every other member of the USC defensive backfield is superior as an all-around athlete, Ellison, who was lightly recruited out of high school, makes up for a lack of eye-popping measureables with intelligence, physicality and a penchant for making the big play. Of concern to scouts, is whether Ellison has the straight-line speed to handle the transition to the NFL, especially considering the three knee operations he's undergone while at USC.
