Williams (6-2, 219, 4.47) is ranked as the nation's 18th-best prospect (No. 1 in Illinois) and as the country's fourth-best linebacker.
"It was cool," Williams said after returning home from an unofficial visit to OSU for the dramatic triple overtime win over N.C. State. "I liked the game and the stadium. It was exciting.
"I liked how the team played. They showed good team chemistry. They had a good attitude. They could have broken up in that situation, but they didn't. I also liked the facilities there. I took a nice tour of the campus."
Williams came to OSU one day after helping Bolingbrook post a 55-8 win over Romeoville. He had 22 carries for 170 yards and three touchdowns on offense and 12 tackles on defense. He had 88 tackles and six sacks as a junior.
"I like (OSU assistant Tim) Spencer," Williams said. "He's pretty cool. I also like Coach (Mark) Snyder, the linebackers coach, and the defensive coordinator (Mark Dantonio)."
Williams said he doesn't have a preference for his position in college.
"They are recruiting me on defense, but they haven't seen me run the ball yet," Williams said. "Maybe they'll look at me there. I really don't care where I play as long as I'm on the field. I think I could make an impact on both sides."
Williams, who holds a 2.52 core GPA, still lists Iowa as a slight favorite. He has one official visit set to Oregon for Jan. 9. Other schools in the running to get visits include OSU, Miami (Fla.), USC, Kansas State and Purdue, Williams said.
"Those are pretty much my top schools right now," he said.
