Jefferson is a stout player with very big thighs and excellent lower body strength. He carries a big gut and needs to improve his upper body power. He displays good balance, quickness and has above average agility with adequate change-of-direction skills. Jason is a tough competitor who gives a consistent effort and plays with solid intensity along with good playing strength. He is instinctive and is quick to recognize blocking schemes, reacting quickly and with strength.

Jason struggles to split double teams due to marginal hand usage and shorter-than-ideal arms that prevent him from getting a good extension into the blocker. He works well in run containment, using his size to get a good lean and push when plugging the rush lanes. Against the run, he shows good strength to hold the point, but really struggles to shed and work across blocks.

He shows some explosion off the snap, but is not really considered someone who can generate a sudden burst consistently. Jefferson will flash good explosion along with ability to snatch and remove along with real good pursuit effort and decent production. When he stays low in his pads, he shows enough lower body power to stack and defeat the one-on-one blocks. There is no question that he plays with good effort and desire, but outside of the short area, his lack of speed prevents him from making plays in long pursuit.

Jefferson is very alert, doing a nice job of reading schemes and reacting in the five-yard short territory. He has some quickness to gain penetration, but with four pressures in 42 games, he is not the type that would cause a quarterback to have bad dreams. He has decent initial quickness off the ball with the lateral quickness and ability to work over trash, but still lacks good separation or a sudden closing burst to get more pressure. He has good upper body bulk, but does not generate enough force to neutralize and make the play in pursuit.

Jefferson uses his hands mostly to get a push and is slow to recoil and gain inside position on the blocker. He lacks the solid rip, swim, and under-arm action necessary to be effective as a pass rusher, having gotten to the quarterback only five times during his career. His struggles to shed hurt him in the pass rush, but he shows some ability to bull rush. When he tackles, he shows good arm extension to wrap and secure. Jefferson is best when utilized in run containment. He needs to add some additional bulk, but also must trim the excessive baggage he carries on his belly. In a 3-4 system, I feel he can be an adequate reserve nose guard, as I do not think he will be as effective working as a two- or three-tech tackle.
