The Nets signed Donta Hall, but he will have to serve as Allen’s backup and DeAndre Jordan’s replacement. The 6-foot-9 rookie’s minutes at the four will be limited, making Kurucs’ vital. “[We] really envision his role of running the floor for us, rebounding the basketball for us, guarding multiple positions for us, offensive rebounding,” Vaughn said. “His energy we’ll need to take advantage of.” “He had a good practice, he’s done a good job of being in drills with wings and with bigs. … We’re trying to make him the best player he can be. So far he’s accepted that challenge and is willing to play any position for us.”
