Brown picked Auburn over heavy competition from four other SEC schools. The 6-foot-3, 315-pound tackle had Georgia, Tennessee, Alabama and Mississippi State in his final five.
The Lanier senior’s final official visit was to Knoxville the weekend before signing day.
Brown announced his decision on ESPN2, he was the final 5-star player in the country to decide.
"My relationship I developed with the coaching staff is excellent," Brown said. "In just sitting around talking to my parents last night I realized it was the place for me."
Brown point to his bond with coach Gus Malzahn and defensive line coach Rodney Garner as the driving factors in his decision.
He admitted he didn't know Auburn's new defensive cordinator Kevin Steele, but is excited to learn more about what he has planned for the defense.
The addition of Brown to Auburn’s 2016 class could be enough to push the Tigers into the top 10 nationally.
"For the next three to four years its' going to be great to watch Auburn football," Brown said.
