He is also eyeing trips to Syracuse and Rutgers, but the Woodson High standout and does not appear close to making a decision as he sorts through his offers, and readies for more potential offers when the spring evaluation period begins next month.
Wallace knows Maryland well, and his relationship with linebackers coach Matt Barnes is developing.
During his recent trip to campus, the time spent with coach D.J. Durkin provided an indication of the Terps' interest in him.
"We had a great conversation," the 6-foot-1, 214-pound Wallace said. "He used to be a linebacker coach, so we made a real connection. He told me about my film, dissected it, and told me the things liked about it. We really bonded. He said I could come up there any time I want."
The visit to gave Wallace a different view from the academic side as well.
"They talk about the academic part, which is really important because I want to be an engineer," Wallace said. "They really went in detail about my major, and I got to see the engineering field. I saw where the players stayed at, the dorms, and everything was modern and luxurious. It was nice."
The trip to Duke was to watch the spring game, which enabled Wallace to see the coaching staff in action.
"I got a chance to see guys going around and hitting each other," Wallace said. "It was fun. I think it is a very important aspect of seeing what school you want to sign with, and you want to see how coaches react to players and what they do, and how they play.
"What stood out was the way the coaches coach and the defensive scheme they run. I like the culture around it."
Wallace's main contact at Duke is linebackers coach Jim Knowles, who is also the defensive coordinator.
"He's a really good guy," Wallace said. "He's straight forward and tells you how it is. He is someone you can listen to."
This weekend Wallace is joining teammate Noah Boykin for trip to West Virginia.
"We're going to meet up with the coaches and see how it is there," Wallace said.
A trip to Syracuse is also in the works for Wallace, who holds a fondness for the Orange.
"I've been interested in Syracuse for a while," Wallace said. "I like the coaching staff. They're nice. I like the school. It's also a top engineering institution. I love ACC ball and I want to see how it is in Syracuse, get a little more feel for it and go from there."
The interest in the Orange stems from his family's basketball rooting interests.
"My family likes Syracuse basketball," he said. "It's a good school, and we talked about it for the last few months."
Rutgers extended an offer earlier this month, and Wallace is trying to schedule a visit for a spring practice.
"They are one of the best schools," Wallace said. "They're also one of the upcoming schools, like Maryland, and they're in the Big Ten. It is a good school, and with football, it's a great coaching staff. Coach Chris Ash, (defensive coordinator) coach Jay Niemann ...I want to check it out and see how it is and go from there."
