During his freshman year, Vincent began the season near the bottom of the depth chart. Joseph Addai was the starter and Shyrone Carey was the backup at the beginning of the season. Vincent, along with fellow freshmen Alley Broussard and Barrington Edwards, split time on the third string. But Vincent beat out his fellow freshmen for playing time, and by the middle of the season, Addai and Carey were injured. He was named the starter in week 7 against South Carolina, and never lost the job for the rest of the season.
