After his career as a player ended, Radomir remained in basketball all his life as an official, primarily addressing the issues of organisation and development of basketball as a sport and improving the rules of the game and the quality of refereeing. Together with Bora Stanković, he worked with the talented basketball players of the BSK basketball club, called OKK Beograd since 1958. Bora was the coach, and Raša was the technical manager. They spent four years together with the club, and their meticulous work produced a remarkable result – the championship title in 1958/59. OKK Beograd produced many talented basketball players, including the first major legend of Belgrade basketball, Radivoj Korać.
