Williams, a 6-4, 220-pound end, visited Clemson earlier this year to watch spring practice. Back in town last week for camp, he arrived on Wednesday afternoon and stuck around thru Friday morning.
"Every time I'm up in Clemson it's a great experience. It's just a special place with great people," Williams told CUTigers in a recent interview.
The 2015 prospect worked at tight end with coach Danny Pearman and defensive end with coach Marion Hobby.
"Coach Pearman is awesome," Williams said. "I worked out with him last year at camp. I know he's a great coach, definitely knows what he's talking about. Working with him, I learned how to be a better tight end and how to be a better player. So I definitely had a great experience with coach Pearman.
"Also, with coach Hobby, I worked out at defensive end for a session as well. I'd met him prior, but had a great workout with him. He taught me some moves at defensive end. He's a great coach.
Williams has camped at Clemson for the last two summers.
If Williams went to Clemson, he could choose either position. That's what Dabo Swinney told him last week.
"I'll evaluate it myself and see what I like better over the next season, so I'll be able to tell before I get there," Williams said. "I love both positions, so I've got to decide which one I'm better at."
Later this summer, he'll make camp stops at Florida and Notre Dame. Williams hopes to also visit Ohio State, Alabama, Georgia and Florida State.
Several schools have offered, including Clemson, Arizona, Florida State, Michigan State, Ohio State, Tennessee and Virginia.
"I'm still trying to take it all in. All of the schools that have offered me are awesome schools. They definitely all deserve for me to look into them, so I'm still trying to do that," Williams said. "Clemson is definitely up there. It's a great school, a special program, but I also have some other great schools that are great programs that have offered me as well.
"I'm still trying to take in everything and sort it out. Hopefully, by the end of the summer, I'll be able to narrow things down a little bit."
Williams hopes to add offers from Alabama, Florida, Georgia and Auburn.
"If those come in, I'll also look at them. After I look at those schools and any other school that offers me, my goal would be able to commit after spring season next year, towards summer," he said. "Or, if I'm ready, I'll commit earlier than that. I just need to be 100 percent sure I'll commit to where I'm going."
As a sophomore, Williams had 80 tackles and 13 sacks on the defensive side of the ball.
