It's certainly a mess but the NCAA allowed it when they let Euro professional players come play College ball this year. Nnaji never signed an NBA contract or played in an NBA game and has played in Europe only I believe since getting drafted. So his loophole fits the Euro model they are allowing now and he's the first example. It's still crazy that he was drafted in the first round and now has 4 years of college eligibility. The motive for Nnaji is financial since why would someone petition to come back to College after leaving for a professional career. He's clearly getting paid more to come to Baylor then staying wherever he was prior. Baylor won't be his last stop either.
