Zion Williamson entering NBA draft after 1 year at Duke Posted Apr 15, 2019 Zion Williamson is leaving Duke after one season to enter the NBA draft. Widely projected as the top pick in the June draft, the AP national player of the year announced his decision Monday. The ACC player and rookie of the year averaged 22.6 points — tied for the league lead with teammate R.J. Barrett. His decision to turn pro came as no surprise. (Associated Press)
