Spring movement: HIGH

There is potential for some serious movement here and even more movement once fall practice begins (we'll get to that in the below section).

First off, Key is expected back this summer after taking a leave of absence for what the school is calling "personal reasons." The junior will, of course, move to the top of the depth chart at Buck for what's likely to be his final season in college.

Christian LaCouture is fully recovered from his ACL tear last season and looks to regain a starting role on LSU's defensive line.

An intense battle is expected in his potential absence this spring, as several young players jockey to replace Key's backup last season, Tashawn Bower. In a small way, Key's expected absence is a positive in that coaches can identify a backup. 

LaCouture's place in the depth chart is still a bit of a mystery. He began last spring as LSU's nose tackle, as you'll remember, and then, halfway through drills, was moved to defensive end. He was expected to start there before rupturing his anterior cruciate ligament in his knee during preseason camp. 

The DE role in which we have Herron starting will be one up for serious competition this spring. Lawrence is the highly touted lineman from Monroe who saw several snaps a game last year, but Herron is a veteran in the program. 

Fall expectation 

Tyler Shelvin, Neil Farrel, K'Lavon Chaisson and Aaron Moffitt arrive this summer.

Tyler Shelvin is a big body that LSU can use at nose tackle.

Shelvin was the state's top-ranked 2017 recruit, according to 247Sports' composite rankings. He could push hard for playing time at the nose tackle position. Chaisson is a Houston product who coaches love and compare to Key. Look for him to challenge as Key's backup.
