Williams, a 6-foot-1 180-pound athlete, is receiving letters from Clemson, Colorado, East Carolina, North Carolina, and N.C. State.
Last week, a member of the Pirates' coaching staff dropped by Garner and invited Williams to their junior day. He also hopes to take unofficial visits to Clemson and N.C. State.
Over the course of the next few months, Williams plans to display his ability as a free safety that Garner head football coach Nelson Smith raves about.
"He's tremendous athlete," said Smith. "He's an excellent cover guy and just really throws his body around. He'll put a lick on you."
Williams credits much of his development to his experiences playing alongside four-star recruit Chris Culliver, who signed with South Carolina earlier this month.
"It's been a good experience working with Chris Culliver getting me better," said Williams. "I've kind of progressed as he progressed. I hope to make a statement this year."
In addition to his role on defense, Williams will see reps on offense at wide receiver this fall.
A three-year starter for Garner at free safety, Williams was the fourth leading tackler for the Trojans last season. He also intercepted six passes and returned a fumble for a touchdown.
