"It feels great knowing that Georgia is a great school, organization and coaching staff," Williams, 5-foot-8, 165-pounds, said.
Williams joined a flurry of commitments at Dawg Night, becoming the fifth pledge, covering three classes and three states.
Truthfully, Williams thought about committing earlier this week, but wanted to hold off until Dawg Night to make sure of his decision.
"They had told me earlier this week about my offer," Williams said. "I was still deciding and my family and I talked it over. I made the decision tonight. It feels great."
Williams ran a 4.28 in the 40 Friday, easily the fastest time of the night.
