There have been a few threads that have touched on the Euroleague. Mainly with regard to translation of stats to NBA.
I stumbled on this story https://bleacherreport.com/articles/278 ... yle-rights
I still wonder if Euroleague & NBA will work together in some heightened way in future. Doesn't seem an imminent priority to either but I think there are several possibilities that might be fruitful. A well-funded, more visible under 21 league. A senior league (probably 3 or 4 man). A better, longer summer league. Draft picks being assignable to European teams (pay level and who pays would need further study. could be specified or let experiments occur for awhile).
