MILWAUKEE (AP) – The Milwaukee Bucks have taken 18-year-old Giannis Antetokounmpo, a 6-9 forward from Greece, with the 15th overall pick in the NBA draft.   The Bucks had been projected to select a guard Thursday night to replace shooting guard Monta Ellis, the team’s leading scorer last season, who opted out of his contract to become a free agent.  In addition, starting point guard Brandon Jennings is a restricted free agent.  Instead, they went with Antetokounmpo, who averaged 9.5 points and 5.0 rebounds per game for Filathlitikos in Greece’s second division.
