the adoption of the ABA's three-point basket and the use of three referees per game. The NBA adopted the three-point basket in 1979 and adopted the three-man officiating system for the 1978–79 season, although the league returned to two officials the next season. The three-official system returned in the 1988–89 season and has been used by the NBA ever since. As an administrator in the ABA and NBA, he recruited and/or trained young referees, many of whom had long, successful NBA careers, including Joe Crawford, Bernie Fryer, Ed Middleton, Jake O'Donnell, Jack Nies, Jim Clark, Wally Rooney, and Jess Kersey. Also, during his tenure he created the first formal pro basketball referee training program when the NBA contracted with the Continental Basketball Association, at that time the top pro basketball minor league. Under the program, the NBA selected, trained and financially subsidized the CBA officiating staff and hired the CBA's Supervisor of Officials. The training program's success extended decades beyond Drucker's career. By 2000, nine of the 12 referees who officiated the NBA Finals were graduates of the CBA training program. By 2008, 96% of all NBA referees had trained in the NBA's minor league training programs. Today, minor league training and development is the accepted norm for an NBA officiating career. Also during Drucker's tenure as Supervisor, he instituted the first professionally administered psychological profiling for NBA referees, to evaluate what personality traits were most common among great referees. Among the findings, said Drucker, was that to be a great referee "you've got to love [basketball] to succeed at it." After his retirement as Supervisor, the NBA honored him as an "All-Star" referee in the first three NBA "Legends" Games, which showcased retired NBA all-stars in an old-timer's game during NBA All-Star Weekends. Always a bit of a showman, he hit All-Star Coach Red Auerbach with a technical foul in the 1984 game, eliciting laughter from players and NBA executives, and fittingly, renewed anger from Auerbach. Drucker's basketball career began as player where he learned the game from the first generation of basketball superstars. He played high school basketball at Erasmus Hall High School in Brooklyn starting in 1937, in an era when there was no 3-second rule, goal tending was permitted and there was a jump ball after every basket. He played college basketball at City College of New York (CCNY) under Hall of Fame Coach Nat Holman.
