There are two kinds of defenses at LSU: one with Arden Key in the fold and one without.
The kind with Key will be on the field this Saturday at Mississippi State.
That's a big deal. Key came into the season as a preseason All-American after he tallied a school record 12 sacks last season as a sophomore.
His return from offseason shoulder surgery will let LSU defensive coordinator Dave Aranda put Key and true freshman K'Lavon Chaisson on the field at the same time.
Chaisson has shown to be a respected pass rusher in Key's place through the first two games this season, and now both can rush from the edges in the third-down "Cheetah" package put in by Aranda this season.
