"It was a real good time, everything there is real smooth," said Williams. "It was good just spending a lot of time with the coaching staff."
Williams was offered by UCLA last summer after the Bruins' summer camp, and he attended a handful of games this fall.
But until Saturday, he hadn't spent a lot of one-on-one time with the UCLA coaches.
"I saw all of the coaches, but I really spent all of the time with Coach (Jeff) Ulbrich," said Williams. "We talked a lot and he showed me the position and some film and how they'd use me if I went there. He's a really cool coach and I get along great with him."
Williams has 17 offers, from Arizona State, Boise State, California, Colorado, Houston, Michigan, Michigan State, Mississippi State, Nebraska, Ole Miss, Oregon State, Tennessee, Texas Tech, UCLA, Utah, Washington and Washington State.
And with so many offers, Williams said he doesn't see an early decision happening.
"I want to go through the whole process and take my visits and take my time," said Williams. "I don't even have a real favorite, I'm still pretty wide open."
Williams had a slew of Pac-12 offers, but it was a pair of offers last week that really opened his eyes to the recruiting process.
"When I got offered by Ole Miss and Michigan, that was like, wow," said Williams. "I was just watching on Signing Day when Ole Miss was getting all of these bigtime guys and now they're offering me."
Williams said all of his attention is coming as a linebacker, with Nebraska the lone school to offer him as a safety. But which linebacker spot remains to be seen.
"Some like me as an inside and some like me as an outside, but I'm good playing either spot, it really doesn't matter to me," said Williams.
Williams, who plays with the Frat Boyz 7on7, is already selected to the U.S. Army Bowl.
The MVP of the linebackers at the Los Angeles NFTC last spring, Williams plans to return to the SoCal NFTC and will play at the Badger 7on7 next month.
