His father, Jim Jeffcoat, won two Super Bowls with the Dallas Cowboys and is an assistant coach at Colorado. Highly recruited Texas native who also lettered in basketball (four years) and ran track (three times). Saw action in 2010 as a true freshman, making two starts at defensive end, and posted 15 tackles, six tackles for loss and 2.5 sacks with one batted pass. Sprained his ankle against Nebraska and missed the next four games. In 2011, posted 71 tackles, a team-high 21 tackles for loss (third in Big 12) and eight sacks with three batted passes in 13 contests, with 12 starts coming at the Buck position (hybrid DE/LB). Only non-start was against Baylor when Texas opened in the dime package. Suffered a ruptured left pectoral muscle against Texas A&M in November but put surgery off until January. Had a monster game against California in the Holiday Bowl with eight tackles, three tackles for loss and two sacks. Did not participate in 2012 spring practice while recovering from surgery. Returned in the fall and started the first six games at the Buck position, recording 31 tackles, 11 tackles for loss and four sacks with one batted pass and two forced fumbles. Had a fumble return touchdown against West Virginia, his first career points. Continued his run of serious injuries when he ruptured his right pectoral muscle against Oklahoma and underwent season-ending surgery Oct. 19. Still finished second on the club in tackles for loss and sacks despite only seeing action in six games. Returned in 2013 and won the Hendricks Award after pacing the Longhorns defense with 86 tackles, 22 tackles for loss and 13 sacks with three batted passes, his first career interception vs. Iowa State, two forced fumbles and one blocked kick in 13 contests. Team captain.
Good body length and size-speed ratio. Flashes some quickness and shock in his hands to swat and control blockers. Football smart. Solid instincts and overall sack production. Has NFL pedigree. Has a 36-inch vertical jump and recorded a 6.97-second 3-cone drill, second-best among defensive lineman at the combine.
Needs more time in the weight room, as evidenced by 18 bench press reps at the combine, and has a very underdeveloped lower body. Tight hips. Has been slowed by injuries throughout his career and it has affected his physical development. Lacks the base strength to set the edge. Gets rooted out of the hole vs. the double team. Cannot drop his hips and turn the corner. Very inconsistent effort -- average competitiveness and desire.
Developmental 3-4 rush-linebacker prospect with the pedigree and sack production to warrant interest. However, Jeffcoat will need to get stronger and improve vs. the run to ever become more than a backup.
