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, Willie Williams, Joel Tupper and Yancy McNight. He was the ninth Lion overall 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 on special teams. He was the first player from Southern to be invited to the NFL Combine.
Professional career
Barbre was the highest-ever drafted player to come out of Missouri Southern until Brandon Williams. He joined Richard Jordan and Jim Hoots both of whom went in the seventh round, as the only players to be drafted from the school. Barbre joined current NFL and Southern alums Rod Smith and James Thrash as one of three former Lions in the NFL.
In three seasons with the Packers, Barbre struggled to find a role on the team. Originally tried at left guard for two seasons, Barbre failed to earn a starting spot and was tried at right tackle for the 2009 season. Barbre began the season as the starter, but was ineffective and soon removed from the starting line-up.
Philadelphia Eagles
Barbre signed with the Eagles in 2013. He played left tackle against the Packers in week 10 when starter Jason Peters was injured. Barbre played effectively and was the top reserve offensive lineman for the remainder of the season. On June 3, 2014, Barbre signed a 3-year extension with the Eagles. Barbre suffered a season ending ankle injury in the opener on September 7, 2014 against the Jacksonville Jaguars. He was placed on injured reserve on September 9. In 2015, Barbre started all 16 games for the Philadelphia Eagles. Under new coach Doug Pederson in 2016, Barbre won the starting left guard position.
Denver Broncos
On July 26, 2017, the Eagles traded Barbre to the Denver Broncos for a 2019 conditional late round draft pick. He played in all 16 games with four starts at right tackle in 2017 for the Broncos.
