 Some of the teams had players that traced their ancestry to the teams they represent and were allowed to play for that team, such as Germany (US-born Chris Kaman) and Israel (US-born David Blu, who as Jewish was entitled to Israeli citizenship from birth).Other teams naturalised players participating in their country's league system, among them Spain (Congolese-born Serge Ibaka), Croatia (US-born Dontaye Draper), Bulgaria (US-born E. J. Rowland), Belgium (US-born Marcus Faison), and Poland (US-born Thomas Kelati, who qualified for Polish citizenship through marriage to a Pole).Montenegro and Macedonia each naturalised US-born players who had never played in their league system, but had played in neighbouring Serbia, respectively Omar Cook and Bo McCalebb.
