At 6'2" and 225 pounds, Jefferson is an exceptional athlete who moves like a college player already. He's a versatile 'backer who can play across the second level, as well as the 3-4 outside linebacker position.
The Texan has excellent instincts, and he can even match wits with quarterbacks by making checks in the pre-snap phase of a play. Jefferson rarely takes a false step when attacking the line of scrimmage, as he explodes out of his stance after making his reads.
He doesn't get tricked by misdirection and play-fakes frequently, which allows him to seek the ball quicker. Jefferson is advanced for a high school player when it comes to hand-usage and block-shedding. He knows how to properly strike targets at the point of attack, then he quickly sheds to get free and back on track to finding the ball.
Jefferson's athleticism and range allow him to track running backs across the box with ease. He also has the explosiveness to crash off the edge as a speed-rusher. Finally, Jefferson has the movement skills and fluidity to buzz back into coverage on passing downs to insert himself into passing lanes.
