Bob Delaney, the NBA's Vice President for Referee's Development and Performance, will no longer oversee the league's game officials, league sources tell ESPN. The NBA has been pursuing a more data-driven and analytical management structure over the NBA's referees, integrating searching more technology as part of its officiating program. Hired as the NBA's president of league operations in 2016, Byron Spruell has been working to reshape the administering, training and recruitment pools of the league's referees. He's directing the NBA's search, which could include a retired referee in a high-ranking management role reporting to a new director, sources said.
