More recently, he put that top five in order - and named Notre Dame his leader.
"It's Notre Dame, then Wisconsin, Clemson, South Carolina and North Carolina," Williams said. "It's been like that for a while now, in my head."
Williams has a strong rapport with Irish running backs coach Tony Alford.
"I really like the coaches at Notre Dame," Williams said. "Coach Alford is a cool guy, and he keeps it real. He's very straightforward with me about everything."
"The tradition there, too and how Notre Dame uses their running backs are other the reasons (why Notre Dame is running first)," Williams added. "They spread their running backs out and get them involved lots of different ways."
The 6-foot, 202-pound running back is planning on making his commitment before his senior year starts. Before that time approaches, he'd like to take some visits."Hopefully, I can get out to Notre Dame this summer," Williams said. "My parents and I have to sit down and talk about that. I'm not sure what other places I'm visiting yet." Even if he doesn't make it to Notre Dame in the next couple of months, Williams wouldn't shy away from pulling the trigger for the Irish without ever having visited campus.
"Yeah, it's possible," he said.
Ideally, Notre Dame would sign two running backs in the class of 2015. Having signed none in 2014, the Irish still possess quality underclassmen depth at the position, namely Tarean Folston and Greg Bryant, who signed with Notre Dame in 2013.
"Coach Alford and I talk about that all the time," Williams said. "I want to be an elite running back and that competition would make me better. They use more than just one running back, and I would have a shot at playing a lot."
