The 5-11, 190 pounder is now up to 23 offers with the five new ones.
"I'm still open to everyone, I just want to take some visits around, and see how I best fit," said Walls.
Walls, though, has plans to visit UCLA this spring or summer.
"My uncle lives in Beverly Hills, so he's right next to UCLA," said Walls. "I went there when I was a real young kid, but I don't remember it, so I have to go back and check it out."
Walls said that head coach Rick Neuheisel himself offered him.
"Coach Neuheisel was who extended the offer, but I talked mostly with Coach (Clark) Lea," said Walls. "I talked with them both the other day. We had a good conversation and they watched my film and said they were extending a scholarship to me to the program. UCLA is a great university, ranked in the top 10 and it has a really big alumni group, so it's definitely a good thing."
Stanford and Cal are two other Pac-10 schools that have offered him.
Walls said that all the interest in him is coming as a safety, and either spot is fine with him.
"The system we run is only one safety, so I cover a lot of ground. I can run up and make a play on the ball," said Walls. "It really doesn't matter which one I play, I just want to help the team out."
Walls, who said he patterns his game after Ed Reed, said he's open to all comers.
"I grew up kind of all over the place," said Walls. "My mom is an Ohio State alum, so I grew up as a kid liking them. Distance is not a factor for me."
