Duckworth is a two-year starter at right offensive guard who made a rapid adjustment to that side of the ball after originally beginning his college career as a defensive tackle. Known for his overall strength and solid initial pop on contact, he teamed with Ben Grubbs to form what Southeastern Conference coaches felt was one of the best guard tandems in the country.

Duckworth was a two-way lineman at Taylorsville High School. The PrepStar All-American was a four-year starter on the offensive line. He earned Clarion-Ledger all-state honors and was an Orlando Sentinel All-Southern Team honorable mention, in addition to picking up Atlanta Journal-Constitution Super Southern 100 honors. He also received CNNSI.com and The Insiders Top 101 accolades and was named to SuperPrep's All-American squad. Rivals.com ranked Duckworth as one of the top 15 offensive linemen in the nation.

As a senior, he tallied 52 tackles, seven sacks, two fumble recoveries and caused a fumble. He also registered more than 30 knockdowns on offense that year. In addition to starring in football, Duckworth also played center on the basketball team.

Duckworth enrolled at Auburn in 2003, seeing action in 10 games as a reserve defensive tackle. He recorded 12 tackles (10 solos) with two sacks, three stops for losses of 12 yards and blocked a kick. In 2004 spring camp, he lined up at nose guard, but before the season opener, the coaching staff shifted Duckworth to the offensive line. He appeared in 10 games that season as a reserve offensive guard.

In 2005, Duckworth took over right offensive guard duties, starting 10 games. He sat out the Kentucky and Ball State games with left knee lateral collateral ligament damage that would require surgery after the season. He earned All-Southeastern Conference second-team honors during his first year as a starter, as Duckworth registered 22½ knockdowns.

Duckworth repeated as an All-SEC second-team choice by the media, but added first-team honors from the league's coaches in 2006. He was also named All-American second-team by Rivals.com. The right guard started 12 games, sitting out the Tulane contest with a knee sprain. He finished his final season with 30 knockdown blocks and 77 total key blocks.

Negatives: Bit of a waist bender who needs to improve his stamina; he tends to lean into blocks late in games (hands get tired and outside the frame). … Had trouble vs. the speed rush in 2006, possibly an after-effect from preseason left knee surgery. … When he gets erect in his stance and fails to drop his pads, he can be walked back into the pocket. … Not a consistent upfield striker when he plays tall; he tends to lunge at linebackers and whiff some due to his over-aggressiveness. … Needs to improve his base to curtail the problems he has at times with outside speed (gets lazy with his feet and fails to move and gain position). … Sets up well in pass protection, but needs to keep his momentum under control (struggles mentally to adjust to blitzes). … Gets too far forward at times, slipping off his blocks after initial contact. … Gets clumsy with his feet when moving into the second level (goes to the ground at times and is slow to recover) and tries to cut too much. … Needs several reps to retain plays (struggles with a complicated playbook).

Compares to: Cosey Coleman, Cleveland -- Duckworth is a classic road grader with the lower-body power to anchor and the hand punch to shock and impede a defender's forward progress. He plays with good aggression, but sometimes gets out of control, resulting in him lunging and overextending in attempts to get back into the play. He performed better in 2005 than as a senior. Perhaps his offseason knee problems affected him; he struggled vs. the speed rush in 2006, giving up 5½ sacks in his first seven games.

2005: Sat out the Ball State and Kentucky games after having left knee arthroscopic surgery (9/17) to repair his lateral collateral ligament.

2006: Sat out the Tulane game (10/21) with a left knee sprain.
