 On November 18, 2005, in an 84 – 56 defeat of Southern University, Rolle made his collegiate debut, playing 14 minutes and scoring six points while also grabbing three rebounds. Rolle shot 4-of-8 from the field and contributed season bests in rebounds (10) and points (8) to help lead LSU past Nicholls State. He equaled his season high in points against the Vanderbilt Commodores on February 2, 2006, in only nine minutes of playing time. The Tigers surprised many with a Final Four run, and in that game Rolle led the team in rebounds with eight, recorded two points from 1-of-1 shooting, and blocked a shot, all in 14 minutes of playing time. Despite this performance, LSU's opponent UCLA ultimately prevailed, 59 – 45. During the 2005 – 06 season, Rolle averaged 2.2 points, 2.5 rebounds, and 8.7 minutes per game as a freshman, picking up 21 blocks on the year.
