"The visit was great," Allen said. "I didn't tour the campus or anything because I've already done that multiple times.
"I was up there to see a great game and just observe and interact with the team."
While on the visit, Allen says that he realized he will soon be playing college football.
"It's really dawned on me that I'm close to playing college football and it's just an exciting feeling," he said. "I was trying to visualize myself out there and just applying the defensive concepts."
One of the main aspects of the defense that stood out to Allen is just how different it is from what he is used to.
"The defense here is a little different, so I'm sure there will be a little bit of an adjustment period, but it's not anything I'm all that worried about because all the freshman defenders are in the same boat," Allen said.
Allen is excited to see how his college coaches will take advantage of his skills.
"Coach Kirelawich has done a great job recruiting me and just keeping me informed of their plans," he said. "The coaches see me as a rush-end in their base defense.
"They think my skills allow me to get after the quarterback, but I'm also working on pass coverage skills and my ability to contain the run."
In addition, Allen has started to condition for what Arizona wants him to be able to do.
"The coaches ask all of us that we train like we're going to start and they mean it, because you can tell by watching them last year that there is time for young guys," Allen said.
Once he graduates, Allen doesn't plan on wasting anytime getting to Tucson.
"I'm getting to Tucson for the first summer session and I believe I'm supposed to room with Jack Banda, but I'm not for sure on that," Allen said.
"I plan on majoring in business and basically I'm just excited to become a Wildcat and a Pac-12 student athlete."
