In the National Championship game, the Sugar Bowl vs. Virginia Tech, Jackson contributed one solo tackle on special teams.
As a sophomore, Jackson played in all 12 games (including four starts), serving primarily as back-up to senior David Warren at defensive end.
He finished with 37 tackles (including 16 unassisted) on the season, and ranked fourth on the team with 5.0 quarterback sacks, behind Jamal Reynolds (12.0), David Warren (9.0), and Darnell Dockett (7.0).
After Warren's graduation, Jackson took over the left defensive end spot, starting ten games.
He also had eight tackles for loss, which tied Travis Johnson for second on the team, behind Darnell Dockett who posted a school-record 22 TFLs.
In his senior year, Jackson started all 14 games of the season, and registered team-highs in tackles for loss (18.5), sacks (13.0), and quarterback hurries (19).
Due to disappointing performances of Andre Wadsworth and Jamal Reynolds, the potential of “undersized Seminole ends” like Jackson was met with scepticism.
