"The trip went really well," Williams said. "We checked out the facilities, which were really good.
"I got to go there with a bunch of other recruits, including my high school teammates, and we went around the school and looked at everything that goes into being a college student."
While he had a good time, it was also an especially important opportunity for a player coming off a catastrophic knee injury.
It's always been known that Arizona would honor his commitment and it now appears that Williams will greyshirt.
"Sitting out a semester won't hurt me at all," Williams said. "I will just continue to work on getting stronger and getting ready to get back out on the field."
Williams' rehabilitation seems to be going as well as expected.
"My leg is feeling better everyday," he said. "I'm happy where I'm at and it's been helped by the people around me."
"They're both my boys," Williams said. "I've known them since 7th grade and they've been really helpful. Going to school with them in college will be the best.
"When I rehabilitate I think of getting back out there with them on the field and completing our goal."
Although he doesn't arrive in Tucson until January, Williams is already mentally making the transition.
"When I get there it will be good, because I will be able to work full time with the strength coaches and just get used to being in school," he said.
"The coaches think I can make an impact early in my career because I've got good size and I know how to play the game."
