Calvin, who plays at the same high school as former UA big man A.J. Bramlett, is the states' top prospect and is stepping up the recruiting process.
"Right now, the schools that I'm looking at the most are University of New Mexico, Arizona and San Diego State," Allen said. "They all have good things about them and are kind of close to home, so I want to look further into all of them. Arizona has offered me so that's a big deal."
Allen possesses tremendous size and deceptive speed and is being recruited at many positions, but the UA staff envisions Allen on the defensive side of the ball.
"I've been talking with the staff about the program and it's been good," Allen said. "They talked to me about where I would fit in the defense.
"They want their rush ends to be able to get after the passer but also be able to keep contain on the outside, if necessary. They say having good players at my position is very important and they are trying to get athletes there who fit into an attacking, athletic style of play."
Allen says that the coaching staff has made a positive impression on him for numerous reasons.
"Basically, all the stuff I heard was encouraging, and you can tell the coaches go about things in a straight forward, detailed way and just want to keep improving," he said.
Allen has no imminent plans to make a decision, but that could change at any moment.
"I'm not against making a decision soon," Allen said. "I just want to make sure whatever school I choose to play for is the right school for me.
"I want to make sure I look at my best options before I commit."
