"They said they like recruits to take visits later in the season, towards December, so prospects can get around the players a little more," Walls said.
Walls plans to follow that schedule for Northwestern, as well as several other schools he is looking at. In addition to the Wildcats, he has offers from Akron, Eastern Michigan, Louisville, Miami (Oh), North Carolina State, Ohio, Pittsburgh, Syracuse and Toledo.
Many of his offers are from schools in Ohio, but according to Walls, "location won't be a factor in my decision."
In his junior season at James Ford Rhodes high school, Walls ran the ball 100 times for 1270 yards and 22 touchdowns. He was named to the first-team All-City at the end of the season.
Though he has never seen the NU campus, Walls said he could see Northwestern as a solid fit for him.
"It's a good fit for me because I'm really dedicated in the classroom," he said. "I do the best I can as far as my books right now. That's always a plus because it's an academic school, so they work hard on and off the field."
At this point, Walls said that his list of schools is evenly matched, and that Northwestern isn't at an advantage or disadvantage.
"After I take a couple of visits and get to see a couple things, it will probably help me out a lot," he said.
Along with NU, Walls said Duke is the only other major academic school he is considering, though he has yet to receive an offer from the Blue Devils. Though his commitment will likely not come until winter, one factor may in the end determine his choice.
"[The most important thing] is a school that my family supports most and is best for me."
