The morning practice is set to begin at about 9:20 a.m. Here’s what we’re watching: - Leonard and Terrence: Leonard Fournette, the No. 1-ranked recruit in the nation, went through morning practice for the first time Wednesday. Morning practices include mostly veterans and starters. Fournette spent much of Wednesday morning’s practice following behind Terrence Magee during drills. The two worked out together on the practice field for the first time, garnering the most attention from media members. - Mustang sally: LSU showed off defensive coordinator John Chavis’ baby – the Mustang package – during the viewing window for reporters Wednesday. Will we get to see it again? The Mustang package includes six defensive backs, two linebackers and three down linemen. Chaivs and defensive line coach Brick Haley were shuffling players in and out of the drill, seeing who’s best at it. - One the line: There are a few battles raging on the defensive line, and we’ll be watching them Thursday. Defensive tackles Quentin Thomas and Christian LaCouture and defensive ends Jermauria Rasco and Danielle Hunter are all being pushed by young reserves, specifically including tackle Frank Herron and Greg Gilmore.
