Many are seasoned veterans and a select few are new to the roster, but all 50 Tigers figure to make an impact on the gridiron in 2015.
So we hope you enjoy this list, updated once each weekday and compiled by the TSD staff of Ben Love and Hunter Paniagua (who, naturally, had disagreements of their own along the way).
Today the countdown picks back up with a senior linebacker at No. 15, hard-hitting Lamar Louis.
REASON FOR OPTIMISM
The arc of Louis' career in Baton Rouge has continued to trend in the right direction, leaving the distinct impression the best is still to come from the Breaux Bridge native, who has started 15 games and participated in 36 contests over the past three years.
2012 (Freshman): 13 tackles, 2 QBH
2013 (Sophomore): 25 tackles, 2 FR
2014 (Junior): 29 tackles, 2.5 TFL, 3 PBU, 2 QBH, 1 FF
Basically, the more chances Louis (6-0, 229) has been given, the more he's produced. The rising senior is expected to reprise his starting role on the strongside, opposite Deion Jones (No. 17 on our countdown). With his physical nature and experience, Louis provides a great run-stopping option in the linebacking corps next to middle man Kendell Beckwith. The more traditional an offense LSU faces, the more valuable Louis will be.
STILL LEFT TO PROVE
Probably the biggest thing going against Louis is his ability to stay on the field all three downs. That's also the reason his tackle total stood at just 29 stops in 2014 despite the fact he started 10 ballgames.
A season ago then-coordinator John Chavis preferred to substitute for Louis when the Tigers went into two-linebacker sets, bringing in an extra defensive back. The way things are shaping up heading into this fall, it could be more of the same, even with Kevin Steele aboard as defensive coordinator. So if Jones and Beckwith remain on passing downs, that will strip some playing time an impact opportunity away from Louis.
He's also not the most fleet of foot, something that could be a deterrent in Steele's system, which we keep hearing is aimed at bringing heat from the edges. Still, coverage issues aside, there aren't that many options at linebacker, and Louis represents stability and a proven tackler. If he can take the next step, and become less of a liability against the pass, this ranking may be too low for a player already known as a thumper.
