Jefferson's performance, or lack thereof, left a lot to be desired at the combine. He didn't compete in most of the generic drills, but in the ones that he did, his performance was mediocre.
He finished second-to-last among safeties with a 4.75 40-yard dash, which demonstrates that the Oklahoma product is strictly a strong safety prospect at the next level. In addition, Jefferson's 17 bench press reps were far below the pacesetters at that position.
This means little for a defensive back.
I was, however, disappointed in his position-specific drills. He showed a lack of fluidity in coverage and failed to impress on his backpedal. These are two things that should concern scouts.
Jefferson did not run the 40 at Oklahoma's pro day, but put up a decent 4.18 time in the 20-yard shuttle (per nfldraftscout.com). Again, this would have ranked him in the middle at the combine.
This young defensive back was looking to push himself into the conversation for a second-round look following his senior season, but his performance seemed to make that a dramatic long shot at this point.
