Meanwhile, the order of the draft is based on the draft lottery which takes regular season success, or lack thereof, into account. As it pertains to the age eligibility, 18 and 19-year-olds are eligible to be drafted. However, 18-year-olds must turn 18 by September 15th of their draft year. Consequently, there are some instances where a player can be drafted while they are still 17 years of age.
