Dardar enrolled at LSU in 1979 to play defensive tackle. He injured
cartilage and
ligaments in his knee before the season started, so he was sent to the
junior varsity team for rehabilitation. Though he made it back to the varsity team during the season, Dardar never played in a game, and he criticized defensive line coach Lynn LeBlanc for convincing him during team practices that he would be playing. While Dardar was frustrated by his lack of playing time, he said he was determined to play for LSU rather than transferring to another school. In Dardar's first game as a starter, a 21–0 win against
Kansas State on September 13, he recorded seven
tackles, blocked a
field goal attempt, and registered a fourth-down
quarterback sack at the
goal line. He ended the season with 77 tackles (nine
tackles for loss) and five sacks. Going into the 1981 season,
Bill Elko joined the LSU defensive line as a transfer from
Arizona State, but Dardar and Marshall were the starters at defensive tackle, while Greg Bowser and Terry Roussel competed for the starting position at nose guard. After LSU lost their first two games to top five teams (Alabama and
Notre Dame), Stovall announced that Dardar would play at both nose guard and defensive tackle, but would spend most of his time at the former. That season he recorded 77
tackles (14 tackles for loss), recovered four
fumbles, and blocked two field goal attempts. By his senior season in 1982, Dardar had increased his weight to 255 pounds (up from 212 pounds his freshman year) and had taken 0.2 seconds off of his 40-yard dash time. Jenkins said that Dardar had also become more physical and played with better technique. LSU beat Alabama that year for the first time in 12 seasons, holding the Crimson Tide to 132 yards of total offense, and the
Associated Press named Dardar and the other members of the LSU
front seven, collectively, as its regional defensive lineman of the week. The team finished the regular season with an 8-2-1 record and went to the
Orange Bowl against
Nebraska, where Dardar was lined up opposite
Dave Rimington, the Cornhuskers'
center who had won his second
Outland Trophy, an award given to the nation's best
interior offensive lineman. The Cornhuskers gained 218
rushing yards in a 21–20 victory, but the head coaches of both teams praised Dardar's play and noted that Rimington did not dominate the matchup. Dardar was named a First Team All-SEC nose guard by both the
Associated Press and
United Press International that year, and the Touchdown Club of Atlanta recognized him as its SEC defensive lineman of the year. By the end of his senior season, Dardar was ranked in the top five in career sacks (15) in school history. Dardar said that he was hesitant to report to a USFL training camp since they started so soon after the end of the college football season. After the Generals signed the highly regarded running back
Herschel Walker as a
free agent, the team gave up on negotiating with Dardar and all of their top four draft picks. Three months later, Dardar was selected by the St. Louis Cardinals in the third round (71st overall) of the 1983 NFL Draft, While he was at LSU, Dardar met a fellow student named Lorraine, and they later married and had three children. ==NFL career==
