The 6-4.5, 242-pound athlete from Salem Hills (Utah), who plays quarterback and middle linebacker on the prep level, endured cracked ribs and a wrist injury to lead his team to a 10-2 record and secure a spot as one of six finalists for the U.S. Army Player of the Year Award.
Gustin, seen by most as a defensive end/outside linebacker prospect, is rated by Scout as a four-star player, the No. 6 defensive end in the country and the 46th best overall prospect.
But where would Gustin, who has LSU in his final eight, play for the Tigers should he sidestep West Coast favorites USC and Arizona State and trek to the bayou?
There was talk early in LSU's courtship of Gustin that he could potentially play some at quarterback for the purple and gold, an intriguing idea for a player recruited by everyone else as strictly a defensive target.
His high school numbers show Gustin can sling it and hurt defenses on the ground from his signal caller position.
According to Scout's Doug Kimmel, Gustin in his senior campaign threw for nearly 3,000 yards while rushing for just under 900 yards.
But it's hard to deny the physical edge to Gustin's game. A weight-room warrior, he was even more devastating on the defensive side of the ball, recording, per Kimmel, 152 tackles, 29 tackles for loss, 10.5 sacks and two interceptions.
Given the Tigers' well-documented issues at quarterback, the thought of adding another dual-threat guy to compete at the position is a sound one. The reality is, though, if LSU can land a player this strong and physical at his size, Gustin would almost have to play for John Chavis and Brick Haley in the front seven.
LSU also already has a quarterback committed in 2015 in Texas native Justin McMillan. The Tigers do not, however, have a linebacker pledge in the class and have only one defensive end committed, Karr's Isaiah Washington.
Then there's the inevitable attrition coming to the LSU roster. Kwon Alexander could leave the linebacking corps this offseason while Lamar Louis and Deion Jones have only one year of eligibility remaining. The situation at defensive end is similar as Jermauria Rasco is graduating and Danielle Hunter could turn pro.
There's still a long way to go for LSU in this hunt. Gustin is reportedly still eyeing Arizona State, Arkansas, Florida State, Notre Dame, Ohio State, Oregon and USC on top of the Tigers. Key for LSU will be landing the player's fifth and final official visit in January.
Just know that if the Tigers and lead recruiter Bradley Dale Peveto are able to pull off some magic in the mountains of Utah, the player they're bringing down to Louisiana is a virtual lock to end up on defense.
