But the Cardinals have made up a ton of ground.
The 6-foot-9, 220-pound said the U of L staff is "coming after me really hard," and said he's hoping to visit U of L this summer or fall.
"I talk to coach (Kevin) Keatts a lot," Okonoboh said. "To be honest, I talk to Louisville and they're one of the only schools I talk to on the phone. I let (his AAU and high school coaches) handle all the calls and stuff like that.
"Louisville, I talk to a lot and UNLV was one of the recent schools I have talked to. But when most call, I let the coaches handle all of that."
Other schools in the mix include, Indiana, Duke, Cincinnati, Connecticut, Kentucky and several others.
While his parents came to the U.S. in 1994 from Nigeria, Okonoboh said he has grown up on the East Coast. But he said distance didn't matter in a school.
"(Louisville) has been talking about a visit," he said. "I juts know they are a winning team. I know a lot about coach Pitino and the way he coaches and stuff like that from the other guys. I like Louisville a lot."
Okonoboh said Keatts has been telling him about the No. 2 class the Cardinals' already have in '14 with three top-40 guards.
"He has been talking about getting a class together and being a power again, stuff like that," he said. "They're really coming after me hard."
Okonoboh is the No. 37 player in the class and the No. 5 center.
