Madubuike made a name for himself as a sophomore in 2018, earning the team's defensive player of the year award after leading the squad with three forced fumbles and 6.5 sacks.

"I'm just not completely bought into the interior defensive lineman being enough of a difference maker to overlook the needs in the secondary."
Fulton was considered LSU's top corner in 2019 as freshman Derek Stingley Jr. also emerged, creating a dominate tandem for the Tigers.
Fulton led LSU with 14 pass breakups in their undefeated season.
