Barbre was a consensus All-American, All-MIAA and All-Region first-team selection in 2006. He helped lead an offensive line that saw quarterback Adam Hinspeter become just the second passer in school history to throw for 2,000 yards twice in a career. The offense amassed 3,461 yards for the season, including 2,527 passing. He finished with a career-high 94 knockdowns at left tackle and also excelled on the punt coverage unit, coming up with seven solo tackles.
 
Barbre was Southern's first All-American since Josh Chapman in 2002, and was the first to be named first-team since Richard Jordan in 1996. He was the fifth offensive lineman at Southern to be named first-team All-American joining the likes of Terron Jackson (1972), Willie Williams (1976), Joel Tupper (1982) and Yancy McNight (1995). He was the ninth Lion at the time to be named first-team All-American.
 
For his career, Barbre started 33 of 37 contests. All but one of those starting assignments came at the demanding left tackle position. He was credited with 254 knockdown blocks and registered ten tackles (nine solos) on special teams. He was the first player at the time from Southern to be invited to the NFL Combine.
 
Barbre also has a rushing touchdown to his credit as he was part of a memorable formation that saw the Lions line up with 11 offensive linemen in a goal line formation as Barbre ran in the ball for a touchdown just days after then Lions head coach John Ware tragically died during Homecoming week. The formation and play was done in honor of Ware who was a former offensive lineman and helped coach the group.
 
Barbre was drafted in the fourth round of the 2007 NFL Draft by the Green Bay Packers. He played for the Pack from 2007-2010. He played for the Seattle Seahawks and the Miami Dolphins during the 2010 season and then was back with Seattle for the 2011-2013 seasons. He has since been playing for the Philadelphia Eagles where he is a starter at left guard.
