He played defensive end in college football at Stanford. At 6-foot-4, 280 pounds, he ran the 40-yard (37 m) dash in 4.76 seconds, and was known for having a quick burst off the line. Lorig did not work out while at the combine due to injury. In his first two years at Stanford, Lorig played tight end and wore number 80. In his freshman campaign, Lorig played in all 12 games where he contributed on special teams and served as the offense's blocking TE, often lining up in the backfield as an H-back/fullback. He recorded 10 catches for 100 yards. He was then asked by the new coaching staff to switch to defensive end for his junior year and proceeded to record 39 tackles, including 6 tackles for loss and 3 sacks in 2008, and had 37 tackles, 7.5 tackles for loss and 2 sacks in 2007. His NFL prospect status took a severe hit in 2009, when he sat out most of the season because of a torn pectoral muscle.
In his five years at Stanford he started 25 of 29 games, and had 95 tackles, 16.5 tackles for a loss, and 4.5 sacks, earning Honorable Mention All-Pac 10 as a junior, and All-Pac All-Academic team twice (2008, 2009).
