LaMelo Ball has shut it down for good in Australia with a foot injury, but still should be a top-three pick in June’s draft. According to a source, the Knicks never got a chance to see the 6-foot-7 forward play live Down Under. Brass had plotted the trip for this month. In Ball’s last two games in the Australian National Basketball League in late November, he struck for consecutive triple-doubles. Par for the course. Maybe it won’t matter. There’s no guarantee president Steve Mills or general manager Scott Perry will make the Knicks’ lottery selection in June. To their credit, Mills and Perry have assembled six first-round picks in the next four drafts.
