Vincent was the starting tailback for 5 games in the 2006 season, after recovering from his knee injury. However, his senior season was the least productive of his four years at LSU. He was part of a five-man running back rotation (which also included Jacob Hester, Broussard, Keiland Williams and Charles Scott), and he finished 6th on the team in rushing at the end of the regular season with 139 yards. He averaged 3.1 yards per carry, lowest among the five running backs. However, in the 2007 Sugar Bowl, he had his best game of the season, gaining 71 yards on 12 carries.
