Though currently committed to North Texas, Walling says SMU is basically too great of an opportunity to pass up.
Walling, a 6-foot-6, 270-pound offensive tackle out of Lake Highlands High school (Dallas), has been committed to the Mean Green for a few months. But in mid-December, SMU came into the picture and offered him a scholarship.
"When I originally committed to UNT, it was a solid commitment. I saw myself going there no matter what," Walling said. "I had not heard anything from SMU ever, so it never even registered in my mind."
Last month, running backs coach and interim offensive line coach Wes Suan called Walling and told him the Mustangs were interested. Walling recalled June Jones giving him a ring the following day and telling him he watched the film and that "there was nothing else to see."
"He offered me right then," Walling said.
Walling is taking an unofficial visit to SMU today (Wednesday). He's been on campus before, but this will be his first time to really see the academic buildings, dorm rooms and talk to players and coaches in person.
He plans on taking his official visit Jan. 27.
"I'm keeping an open mind, but the more and more I've talked to [SMU] coaches, it's just too good of an opportunity to pass up," Walling said. "I told the UNT coaches that, and I've been honest with them up front. They haven't backed off any, but I have told them I'm considering SMU. They all understand."
Even if Walling falls in love with SMU on his unofficial Wednesday, he says he won't make any hasty decisions until he talks to North Texas.
He said head coach Dan McCarney is coming to his house for an in-home visit on Monday and he just doesn't see himself de-committing or committing anywhere else until afterwards.
But Walling did say there really isn't anything North Texas will be able to do to convince him to stay. The only way he won't come to SMU is if he takes his tour of the campus and it isn't what he though it would be like.
"Maybe [SMU] won't be all I thought it would be," Walling said. "I've only been up there once. It all depends. I'm not sure what [McCarney] could say [to make me keep my commitment]. Maybe if there's something I don't like about SMU I'll be more open to what he's saying and what he's trying to sell."
Walling said that SMU beats out North Texas in every one of the categories he deems important when picking a school.
"The academic opportunity, the Big East, which is a big deal to me, and I'll be closer to home so I can see all the stuff my brothers are doing and they can come watch me," Walling said. "Plus the winning tradition, the fan base and [SMU] has better facilities to be honest. All that plays a factor."
Though he has a great relationship with UNT's coaching staff, which he says makes it hard to want to de-commit, Walling said academics is the biggest difference between the two schools and that is important to him.
"The biggest difference to me is the academic education I'd get and job opportunities after graduation," he said. "I'm thinking way down the line, how graduating from SMU would look compared to graduating from North Texas."
Walling doesn't know anyone who goes to SMU, but did mention his high school valedictorian is going to SMU and a friend of his plans to play soccer there.
Walling received an in-home visit from Suan and Jones last week and said they basically took him through the routine of what it's like to play football at SMU, told him stories and talked about the future of the program.
Walling said the Arizona State job didn't come up in conversation.
"Coach Jones made it clear that he loves where he is, loves SMU and loves the coaching staff," Walling said.
He also said the coaches told him that he would have a chance to compete for a starting job early.
"They said if I'm ready, that's great, and if I need time to develop, that's good too, but they said I can get in and compete right away," Walling said.
Walling plans to major in business.
