Iowa offered a scholarship to Allen, who turned the head of scouts with his performance with the Southwest Illinois Jets at the Spring Showdown AAU event in Merrillville, IN.
"They've been interested in me for quite a long time," the 6-foot-4, 180-pound Allen said. "I thought I played really good this weekend. (The Hawkeyes) were at every one of my games Saturday. They weren't there Sunday. I didn't see (the offer) coming, but it came, and I'm happy that I got it."
"I have a great relationship with the whole (Iowa) coaching staff," Allen said. "Me and my family have been there about three times. I love going there. Me and my family love it. It's a great place to be.
"I like the coaching staff. They're all really nice. I feel like I can fit in with that coaching staff. The fans also are great there. Their support of the basketball team is terrific."
Allen is watching what Iowa is doing in recruiting and on the floor. He likes the progress being made since Fran McCaffery took over the program two years ago.
"I pay attention to all of that," he said. "I know they have a good class coming in next year. They only lost a couple of players and I think they're going to be one of the top teams in the Big Ten next year. That gets me excited that they offered me an opportunity to play for them and that they want me to be a part of their upcoming success."
Allen reports that he's received strong feedback from programs after the Spring Showdown.
"DePaul, Purdue, Illinois and Michigan, they were pretty high on me after the tournament," he said. "Before that, some new ones have been Auburn, Oklahoma, Florida State, Butler and Mississippi State."
Said Jets Assistant Director Dana Morgan: "He probably averaged 23 or 24 points a game for us (in Merrillville). He was rebounding. He was showing that he's an athlete. He's really focused on just being a complete player and losing the stigma of being just a shooter."
"I've been working on my game and been in the weight room to get stronger, quicker and faster," Allen said. "Most colleges thought of me last year as just a knock-down shooter. I need to prove that I can get to the basket and do other things than just shoot."
"I don't really have a timeline (for committing to a college)," Allen said. "Whenever I feel like I'm ready to make a decision and I feel like I fit in with a program, I'll make my decision. Right now, it's real early. I still have the rest of the summer and another AAU season to come next year. I want to take my time right now."
