Williams also claims interest from Louisville, Kentucky, North Carolina, Duke, Miami and Northwestern.
"I'm hearing from big colleges this summer," Williams said. "I'm glad I caught their eye."
Despite being a wing prospect, Williams said he had to focus on getting things done in the paint during the AAU season.
"I thought the summer went real good," he said. "I had a lot of good competition. It was fun. I had fun with it."
"I just had to help rebound," he added. "I'm the tallest player on the team so I had to play inside and out. I grabbed rebounds and pushed the break."
North Carolina has been in touch, and Williams spoke to UNC assistant coach Steve Robinson last week.
"I've been talking to Coach Robinson every now and then," Williams said. "He's been keeping in touch. They are showing interest. Soon I'm going to go up and tour the campus and talk to the coaches and hang out with the players."
Although Carolina hasn't offered him a scholarship, Williams said the Heels are near the top of his list.
"That's a school that is definitely known around the world," he said about the Tar Heels. "The fact that they are interested in me is good. Whenever I make my top five there's a good chance they might be in there."
With that said, Williams said he's far from beginning the process of narrowing his list.
"I'm still open," Williams said. "I'm not going to make my top five until the middle of my basketball season."
