Then the five-star linebacker spent the weekend at LSU during the Tigers' Spring Game. The coaches pulled out the red carpet for him on that visit and impressed him enough to move to the top of his list.
LSU hasn't fallen out of Garrett's favor since, and the nation's No. 1 MLB is set to return to Baton Rouge for an official visit this weekend.
"I'm expecting it to be crazy," Garrett said. "Everybody says Baton Rouge is crazy on game days. And they're playing a team like Texas A&M, so that should definitely make things livelier than usual. I can't wait."
Garrett will fly down Friday with his parents, who didn't come with him during his visit in April. It will be crucial for the LSU staff to leave as favorable an impression on Garrett's parents as they do on him.
"They're looking forward to the LSU experience," Garrett said. "They talk to Coach Miles and Coach Chavis all the time, but they're finally going to get a chance to meet them in person and sit down and talk to them…My parents know what's best for me. Their opinion definitely matters big time."
So far, Garrett has taken official visits to Florida, Ole Miss and Tennessee. This trip to LSU will be his final visit, and Garrett will spend the next six weeks finalizing a decision before announcing it at the U.S. Army All-American Game.
Right now, he says he doesn't have a clear leader out of those four schools.
"I like [LSU] a lot, but every school is pretty much even at this point," Garrett said. "After I make this last official visit, I'll start considering everything about them, and see where I can see myself going."
Garrett said he can definitely see himself playing in Coach Chavis' defense. His reputation as a defensive coordinator was what set LSU apart early in Garrett's recruitment, and he'd like to follow in the footsteps of players like Kelvin Sheppard and Kevin Minter.
Even though the Tigers have had a down year defensively, Garrett still has plenty of confidence that it will turn around in a hurry.
"LSU's defense hasn't played up to the way everyone expects them to play, but that's what they've been recruiting for," Garrett said. "They have a pretty good class this year. They've got some guys that I've seen before, and I'd definitely like to play with some of those guys. Chief knows what he's doing. He's one of the best defensive coordinators in college football for a reason. He'll definitely get things right."
Garrett's no stranger to some of the top talent in Louisiana either. He met several of the state's top recruits this past summer at The Opening and has developed strong relationships with them. He played on the same 7-on-7 team at The Opening as Devante Noil and Leonard Fournette. He's also spoken about LSU with Gerald Willis, Edward Paris and Malachi Dupre.
Garrett said he could see himself suiting up with all those guys.
"Those guys are all elite players in the country," Garrett said. "They have the same mindset as me. They want to go in and play and win national championships. It would be good to have guys on the team with that same attitude as me."
