tell. He moved to the US at 16 to play high school basketball, then went to Kansas after HS. As far as I know he never played pro ball in Europe or Africa.
Not sure about the other guys on your list. They were in basketball youth academies from an early age, run by pro teams, which is the European model (copying soccer there). They probably played some games on the “regular” professional team, but I don’t know if they were actual paid professionals. Are they even allowed to play college basketball if they are already pros overseas?
