So why did Scout.com's No. 6 overall running back nationally drop the two Big Ten powers from his list and move the Cardinals into contention?
"Coach (Tony) Alford is recruiting me and I really like him a lot. He doesn't talk at you – he talks to you. He's a real good (guy)," Oku said. "I (also) know a lot about Coach (Steve) Kragthorpe because he used to coach at Tulsa and recruited me when he was there. And I know they had (Michael) Bush that plays for the Raiders and (Brian) Brohm who plays for the Packers."
"I don't like one school more than any other. They're all pretty even," Oku said. "Those are the schools I feel comfortable with. My dad wants me to make a decision as soon as possible. So I want to make my decision by (early) October."
Here's what will likely happen. Oku, an explosive running back who can go the distance, will make official visits to his four finalists during the month of September before pulling the trigger on a decision early the next month. Louisville will get the first chance to make a big impression when Oku visits for the season-opener against Kentucky on August 31.
"Coach Alford and I already have the official visit set up and done," Oku said. "I'm going for the Governor's Cup and I'll probably fly in on Saturday – the game's on Sunday and leave out on Monday."
When he takes his visits, Oku will be looking for a comfort level with each prospective program. He also wants to find a place favorable for early playing time.
"I want to go somewhere I'm comfortable," Oku said. "I don't want them to pull a front when I go to their school I'm just looking for everything to be mellow. Fancy facilities and all that don't matter to me."
Blessed with explosive slashing ability and sub-4.5 speed, Oku rushed for 1,628 yards and 20 touchdowns as a junior while leading his school to a 10-2 record.
"Balance…feature (back)," Oku described his running style. "I wouldn't say I'm an every down back but you can move me around. Some people say I'm not a burner but I have game speed. I have speed and I guess you could say I'm a receiver/running back."
