BIO: Three-year starter who posted 25/4.5/3 as a senior.
POSITIVES: Well-built run stuffer who plugs the middle of the field. Explosive off the snap with a great first step, can change direction and relentless in pursuit of the play. Gets underneath opponents wedging through blocks, collapses outside defending the run, and plays with both balance and body control. Tenacious, works hard and displays good hand technique getting off blocks. Good closing burst of speed.
NEGATIVES: Lacks height, handled at the point by a single blocker or engulfed by opponents. Not light on his feet and limited skills rushing the passer.
ANALYSIS: A defensive lineman whose quickness gives him a decided advantage against opponents, Jefferson is a competitor always working to make the play. Has growth limitations, yet would be effective as a three-technique lineman or in a system that places him next to a wide-bodied tackle. Will slide into the draft's second day, but could very well turn out to be one of the better bargains this April.
