"How to compete," Chukwu stated. "You're playing against a lot of big men and you're testing yourself. Plus, you get to learn a lot from the pros."
The "pros" was a mixture of current and former NBA players who littered the sidelines at the event, instructing and coaching the prospects.
"That was great," said Chukwu. "They were teaching us other things like life skills, not just basketball skills. It's fun."
What was the biggest difference on the court for Chukwu?
"I had to adjust my shot," he said, laughing. "In high school I'm playing guys that are 6'7 or 6'8, but now I can go against guys that are 7'0 or 7'2. It changes my shot a little bit and that's something I'm going to see on the high levels."
A native of Nigeria, Chukwu is a work-in-progress but that hasn't prevented several programs from extending offers. The 7-foot-1, 225-pounder is a presence in the paint, particularly on the defensive end where he uses his length and athleticism to defend the rim.
"I have a few schools right now," he said. "Virginia, they've been talking to my guardian a lot. I also have Providence, St. John's, St. Joseph's, UConn, [and] NC State. All of them talk to my guardian."
NC State has ramped up their interest recently.
"They've been sending me a lot of letters and talking to my guardian," said Chukwu. "During the season my dad said they would be recruiting me so he told me to watch them play. I've watched some of their games.
"I haven't been there yet for a visit or talked to the head coach, but my guardian has. I have some feel for how they are. I think they are a good team. I think I would fit there if I go there, but that's just from seeing how they play on TV. I need to go down there and see what it's like at the school."
Chukwu is in no rush to make a decision. He's going to consider several factors before picking his school.
"All that matters is finding a place I feel at home and having a good relationship with the people," he said. "I want a place that fits me as a player an where I'm comfortable with the coaches and my teammates.
"Hopefully after the AAU season I can go on some visits and then go from there."
Chukwu is rated the No. 7 center in the country and the No. 49 player overall by Scout.com.
