Sixteen players, including projected top-two picks Ben Simmons and Brandon Ingram, have been invited to attend Thursday's NBA draft at the Barclays Center in New York, league sources told The Vertical. The group of “green room” prospects is smaller than in years past in which 20 to 25 players were invited to the event, reflecting the uncertainty revolving around the draft. The league office and many team front offices are struggling to get an accurate read on the draft outside of the top 10 picks, sources said.
