It came to its peak on Tuesday.
"I committed to South Alabama," he said. "It felt like home. I loved the coaches and I want to be apart of something that's on the rise.
"I called Coach (Joey) Jones after practice and he was very excited. He wants me to be a difference-maker, on and off the field."
The trip to the nearby campus, which Thompson estimates as "maybe 15 minutes" away from his home, sealed the deal for the state of Alabama's top cornerback in the class of 2015.
"It shocked me," he said. "The locker room was great and the coaches made me feel like I was one of the players already."
The No. 54 cornerback nationally on Scout, his parents and family also enjoy the fact that they'll be able to see him play close to home.
"They love the idea," Thompson said. "They wanted me to go to a place I could call home."
Going forward, despite SEC offers, there are no set visit plans. The 5-foot-11, 170-pound Thompson has not ruled out visiting other campuses, though he has already seen several on his offer list -- including Florida and South Carolina.
