He invented the TENDEX system at the age of 20, which later became for many years the most widely used system in the world for rating pro and college basketball players. At age 23, became statistician for his favorite team, the New York Knicks. Wrote nine books with emphasis on TENDEX, including five editions of Basketball Abstract, which became an often-emulated standard for basketball stat books. His TENDEX player ratings were printed for a decade on the NBA website, were used by head coaches of more than half of the league's teams and served as basis for the database of a basketball encyclopedia. Professional basketball leagues based in Europe and Australia formally adopted TENDEX ratings for their players.показать меньше
