Kentucky reserve big man Daniel Orton will enter the NBA Draft, his father Larry said on Wednesday. His son will not hire an agent so he can retain the option of returning to UK next season, the elder Orton said. Orton is expected to be one of several UK players entering the draft. Others expected to enter include fellow freshmen John Wall and DeMarcus Cousins, plus junior forward Patrick Patterson. According to NCAA rules, underclassmen have until May 8 to withdraw from the NBA Draft and retain their college eligibility.
