With a planned visit to Tallahassee in the works, many expected it to come down to the two national powers.
The decision did, but the visit to FSU never happened.
Instead, Williams decided to end his recruitment on Tuesday by committing to Nick Saban and company.
"I committed at 1:30 (p.m.) our time, 12:30 Alabama time," he recalled. "I called Coach [Kevin] Steele then I talked to Coach Saban.
"When I talked to Coach Saban, he didn't know I was going to commit," he continued. "He thought I was going to call to keep in touch and stuff like that. I guess he was kind of shocked, he was like, 'Well we can make that happen!' Then he wanted to make sure my academics were good and all that."
Williams joins fellow Camden County four-star Kalvaraz Bessent on the Tide's class of 2014 commitment list.
"It's pretty cool," he said of playing with his close friend. "It's good to stay close to somebody.
"He actually talked to me everyday in school, asking me where I was going to school. I always told him I would chose soon, and today I made my choice."
For the 6-foot-2, 180-pound Williams, the edge Bama had over FSU was a small one.
"It was either Alabama or FSU," he admitted. "Me and my mom stayed up last night to talk about it, after Kalvaraz called me. We talked about going there together and then me and my mom talked about it some more and I made my choice!"
The recent visit to Tuscaloosa all but sealed the deal for Williams.
"Seeing all the sites, the way the coaches treated us, the practice facility, the weight room, the game field... Everything was just perfect," he added.
The Peach State prospect will work closely with Saban once he enrolls at Alabama.
"I'm playing safety, that's what they recruited me for," he said. "I'm most likely a free safety. I can tackle, I can cover ground, I can catch, I'm a ball-hawking safety.
"Any ball in the air, I'm going up for it."
While FSU was close beforehand, Williams says the 'Noles may not have much of a chance going forward.
"I'm going to shut everything down. Alabama is my school now," he said. "We're probably going to try to get more people to come!"
While Williams and his camp was excited, Saban wasn't the only one surprised by the decision.
"She was excited, because she was actually an Alabama fan," he said of his mom. "It really gave them an edge, that's where she really wanted me to go.
"She was surprised because I was messing with her, telling her I wasn't going there and stuff like that so I surprised her with it. and I have a lot of family in Alabama, they're surprised and happy with it too."
