A native of Plano, Texas, Jeffcoat tallied 21 tackles and five sacks in the last two games of the regular season. On the year, he also led the team with 18 quarterback pressures and had three fumble recoveries, a forced fumble, interception and three pass breakups. Jeffcoat has made some of his biggest plays at pivotal times for the Longhorns. In a 31-21 win over Kansas State in September, Jeffcoat recorded both of his sacks on the Wildcats' final two drives to help prevent a comeback. Against Iowa State, his interception on the Cyclones' final drive helped seal a 31-30 win. His two sacks against Oklahoma came on third and fourth down, with the fourth-down sack coming in the fourth quarter and ending OU's final drive. His 12 sacks and 19 tackles for loss in conference play are more than any other Big 12 player. - Big 12 football
Operating with his hand in the dirt as well as a stand-up pass rusher in defensive coordinator Manny Diaz's aggressive scheme, Jeffcoat exploded a year ago to register more tackles (71) and tackles for loss (21) than batterymate Alex Okafor and tied him for the team lead with eight sacks, but was recognized with "only" second-team honors from the league's coaches despite his big statistics.
The son of former Dallas Cowboys and Buffalo Bills' standout Jim Jeffcoat, Jackson has greater upside as an NFL pass rusher than Okafor but remains a bit hit or miss, at this time.
NFL scouts want to see a big senior season from him, but he simply hasn't responded so far. (10/14/13)
Weaknesses: Despite displaying quickness off the edge and the toughness to attack the body of the edge blocker, Jefferson doesn't do much after initial contact. He struggles to get creative with his rush moves and he doesn't use his hands correctly to shed blocks or keep blockers from his frame. The Oklahoma game was a microcosm of Jeffcoat's senior season -- even his highlight tape is extremely average.
