GoJackets.com spoke to Mario soon after he shared the news with one of the Tech coaches and his family.
"I just got through making it," said Butler. "I called Coach (Buddy) Geis and we were just talking and he was excited to have me. And all of my family was around."
Mario says he didn't tell any of his family prior to today's announcement. Only his high school coach knew.
"No, they didn't know," said Butler. "I surprised the family. They were happy."
Was it hard to keep it a secret?
"Yeah it really was because everyone kept on hassling me about what school I was going to," said Butler. "I didn't even give anybody any hints. After a while they just stopped when they realized I wasn't going to tell them until today."
Butler chose Tech because of the program's all around appeal.
"Because it's an amazing program," said Butler. "It's great academically and athletically and I get a chance to compete. It's really an all around program."
Mario says the Yellow Jackets are bringing him in as a cornerback. He's even sat down with one of the coaches to go over the depth chart and how he'd fit into it.
"I sat down with Coach (John) Tenuta, the defensive coordinator, and he pulled the depth chart out in front of me," said Butler. "He showed me what the depth chart was and what I can come in and do."
Mario, confident in his abilities, says he doesn't plan on being brought along slowly in his first season in Atlanta.
"Nah, no redshirt," said Butler. "I'm coming in right away to play. As long as I can come straight in and compete, I'll be okay."
There is a chance Butler could begin at Tech earlier rather than later.
"Right now I'm deciding: should I enroll in January," said Butler. "I'm just trying to wait and see because I have one class I can take at a community college at the school. And I'm trying to see right now, can I take it at the community college."
Mario thinks there would be a big advantage in getting an early jump into college.
"If I can get started in spring I'll already be coming in and have an advantage over the other freshmen coming in," said Butler. "They'll have to learn everything [in fall] and I'll be already learning the ropes."
Mario is already thinking ahead on how he can help the recruiting efforts. There is another local player he has in mind for wanting to join him in Atlanta.
"I'm going to try and get Troy Pollard, the running back from [Andrew] Jackson [High]," said Butler. "I'm going to try to get him over there with me. They haven't offered him yet but hopefully they will then I'll be able to get him down there."
Butler's was asked what Tech fans can expect to see from him when he arrives.
"I'm just ready to compete," said Butler. "When I get there, I'm going to compete – every day, all day. Hope they like it."
