Seton Hall junior forward Sandro Mamukelashvili has had Zoom calls with close to 20 NBA teams, including the Knicks. The 6-foot-10 native of the Republic of Georgia is testing the NBA Draft waters ahead of the Oct. 16 NBA Draft, and said he’s still undecided about his future plans. The NBA withdrawal deadline is Aug. 3. “I’m taking my time and evaluating all of my options,” he said Friday. “I had a lot of interviews and I want to think about my plans.”
