San Diego needed help at D-end, where Jacques Cesaire and Travis Johnson are both clear to depart as free agents. Nonetheless, it is mildly surprising San Diego went with Liuget over Da'Quan Bowers -- who a couple months ago was a candidate to be the top overall pick -- and Cameron Jordan, who played a 3-4 scheme at Cal.
Liuget insists he has the skill-set to excel in San Diego's 3-4 defense.
"I did it all," said Liuget of his time at Illinois. "1-technique, 3-technique, 5-technique, whatever the coaches needed me to do."
When asked at his Pro Day about the prospect of playing in a three-man front, he responded: "Yes, I most definitely could do that."
DT Corey Liuget
One reason the Chargers may have opted for Liuget over Bowers and Jordan is his motor. He is a hustle player who will work up and down the line of scrimmage. He can chase down scrambling quarterbacks and catch ball-carriers from behind; and when he catches a player, he goes for the strip.
The selection of Liuget continues the youth movement along San Diego's defensive line. He will be part of a rotation that will also feature 2009 fourth-round pick Vaughn Martin and 2010 fifth-round pick Cam Thomas. That trio, along with Castillo and Antonio Garay, should provide the core of Don Johnson's defensive line for years to come.
The selection should also shore up a run defense that had too many holes last season, as highlighted by a devastating December loss to the Raiders in which Oakland racked up more than 250 yards on the ground.
