Ntilikina, an 18-year-old point guard, is widely considered the best prospect in European basketball and one of the most intriguing players expected to be available in the N.B.A. draft this summer. In one recent mock-up, ESPN projected the 6-foot-5 Ntilikina as the sixth overall pick.
According to his teammates, his coaches, his agent, talent evaluators and pundits, Ntilikina (pronounced nee-lee-KEE-nah) is mentally mature, with an enviable collection of physical tools. But with six months to go before the draft, everyone sees there is work to do.
