This is the fifth of a seven-part series starting Sunday and ending Saturday, the first day of LSU's spring football practice.

Depth chart

RB

  • Derrius Guice, junior
  • Darrel Williams, senior
  • Nick Brossette, junior
  • Lanard Fournette, RS sophomore
  • Lost from 2016: Leonard Fournette (NFL declaration)

FB

  • Bry'Kiethon Mouton, junior
  • David Ducre, junior
  • Trey Gallman, junior (walk-on)
  • Lost from 2016: J.D. Moore (temporarily out for spring while recovering from wrist injury)

Spring movement: LOW

The star of LSU's team is the guy at the top of the running back depth chart. 

Guice is a 2017 Heisman Trophy favorite and a sure-fire first-to-second round pick in the 2018 NFL draft. He'll likely break LSU's career-rushing record for yards-per-carry, and he already holds the single-game rushing mark. His place atop the depth chart is as safe as it gets.

The depth is, somewhat, unproven and low on production. For instance, Guice has more yards (1,823 to 1,054), more carries (234 to 206) and more touchdowns (18 to 10) than the three other running backs combined. It's time for Brossette, a U-High product, to evolve into a guy LSU will rely upon, not necessarily this season, but next year.

Bry'Kiethon Mouton should get the bulk of J.D. Moore's carries this spring. 

At fullback, Moore is the starter, but he'll miss the spring while recovering from a wrist injury he suffered last season. He underwent a procedure, and he's in an arm sling. That gives Ducre and Mouton more carries at a position where the backup is oh-so important. Fullback is an injury-prone spot. 

Fall expectation 

Georgia fullback Tory Carter joins the squad over the summer. Scout.com's No. 1-ranked fullback in the 2017 class, Carter is 265 pounds and stands 6-1.

He'll start behind in the experience department. Mouton and Ducre are third-year guys, and Moore, a senior, is solidified as the Tigers' No. 1 guy.
