Answer
EuroBasket League is not a former name of the EuroLeague. The EuroLeague, a professional basketball league for European clubs, has had several names throughout its history, including the European Champions Cup (1958-1991), the FIBA European League (1991-2000), and the Euroleague Basketball (2000-present). The EuroBasket League, on the other hand, is a separate competition organized by FIBA Europe for national basketball teams.
