Williams, a 6-foot-6, 273-pound offensive tackle from West Roxbury (Mass.) Catholic Memorial, will announce between Boston College and North Carolina during the All-American Bowl, Saturday.
Williams says his decision has been made. It's just a matter of announcing it to the public.
"I'd say a few weeks ago I made my decision," Williams said. "There was definitely a lot of talking between my mom and dad. And it ended up just being, just basically, ‘Why not?'"
As of Wednesday evening, Williams hadn't been informed when during the game his announcement would take place.
Up until the Dead Period, Williams says he has remained in constant contact with both coaching staffs.
Sam Pittman, UNC's offensive line coach, serves as Williams' primary contact for the Tar Heels.
"In our last conversation, really it was the same kind of thing the rest of the coaches say – they think I'll be a good fit, they think they have a plan for me, and they think I'll have a lot of fun," Williams said.
Despite all that's weighing on his mind, Williams has been able to enjoy the week.
"It's really a blast," Williams said. "I get to play with all these kids who are going to be the real deal in a few years. I'm sure I'm playing with some guy who is going to be the top player in the NFL in the future. It's really a cool experience and it's an honor to be playing for the U.S. Army and representing my town."
With the East squad being heavy on tackles and light on interior linemen, Williams has played just about every position on the offensive line this week.
"This week, I've actually been playing everything," Williams said. "So I have no idea how I will be used [Saturday]. I've been playing a lot of center. I'm sure I'll see a lot of center during the game."
