The practice of nationalizing players, once limited to smaller basketball nations, is rapidly becoming more widespread as teams seek a competitive edge. A surge in passport acquisitions has been observed in recent years, with more athletes becoming eligible to represent countries beyond their birthplaces. This trend gained prominence during EuroBasket 2025 qualification, highlighting the growing impact of naturalized talent on the international stage.

Understanding the Rules of Nationalization

The regulations surrounding player nationalization are carefully defined by FIBA, the international governing body for basketball. FIBA officials consistently emphasize the existing rules, particularly in response to the increasing number of players changing nationalities. The core regulation stipulates that teams can only roster one naturalized player per match played.

A naturalized player is defined as someone who obtains a passport from a country other than your origin after turning 16. This distinction allows players like Nick Calathes (Greece) and Vezenkov (Bulgaria), who weren’t born in the countries they represent, to play without occupying a nationalization slot.

FIBA Secretary General Andreas Zagklis articulated the organization’s stance in 2022, stating that FIBA nationalization rules are among the strictest in all sports. He defended the regulations, acknowledging the varying ease of obtaining citizenship across different countries. There are some countries where it is extremely difficult to obtain a passport. And others where it is an easier process. Creating a rule that establishes a basis for 212 different nationality laws is extremely difficult. In some cases, you are a national if you were born in the country. In others, if you have an ancestor one, two or three generations back from that country or even if you never set foot in that country..

Beyond Lorenzo Brown: A History of Nationalization

While Lorenzo Brown’s recent nationalization for Spain drew significant attention, he is far from the first foreign player to represent the nation. The practice dates back to the 1960s. In 1964, Real Madrid nationalized Wayne Brabender and Clifford Luyk, two pivotal players for both the club and the national team, following a ban on foreign players in the Spanish league.

Barcelona followed suit, nationalizing Chicho Sibilio and “Lagarto” De La Cruz. Lagarto was part of the Spanish team that won silver at the 1984 Los Angeles Olympics, while Sibilio helped the team to a second-place finish at the 1983 EuroBasket.

Other notable cases include Chechu Biriukov (Russia), Mike Smith, Johnny Rogers, and Kornegay (United States). Rogers and Kornegay gained Spanish passports through marriage, with Rogers replacing Pau Gasol in the Sydney Olympics and Kornegay contributing to a bronze medal at the 2001 EuroBasket.

More recently, Serge Ibaka, Nikola Mirotic, and Lorenzo Brown have contributed to Spain’s success. Ibaka won a European Championship in 2011 and a silver medal at the 2012 London Olympics. Mirotic secured the EuroBasket title in 2015 and a bronze medal at the 2016 Rio Olympics, though his relationship with the national team later became strained. Brown’s nationalization, despite criticism, remains a point of discussion.

EuroBasket 2025: The Impact of Naturalized Talent

Vincent Collet, former coach of France, highlighted a common motivation for nationalization: Most of the time, they are bases, as it is a weakness of European countries. This observation is supported by numerous examples.

Georgia benefited from Thaddus McFadden for four years, and this summer featured Like Baldwin, who played a key role in Georgia’s surprising elimination of France, scoring 24 points in the process.

Montenegro has a history of utilizing naturalized players, including Omar Cook, Tyrese Rice, and Kendrick Perry. Kyle Allman was the latest addition, becoming a key contributor in the point guard or shooting guard position.

In Bosnia, John Roberson filled a crucial role, particularly in the absence of Dzanan Musa. He helped the team reach the round of 16, nearly upsetting Poland with a strong performance. Portugal saw success with Travante Williams, who led the team after a 14-year absence from European competition. Cyprus relied on Darral Willis as its primary offensive threat.

However, not all naturalized players become stars. Players like Khadene Carrington (Israel), Tarik Phillip (United Kingdom), and Darius Thompson (Italy) have had more limited impacts.

Standout Performances: Players Who Made a Difference

Several naturalized players significantly impacted their teams’ performances. Jordan Lloyd and Alen Omic led Poland and Slovenia, respectively, to the quarterfinals. Lloyd stepped into the role previously held by AJ Slaughter, becoming Poland’s best player and leading them to a round of 16 victory over Bosnia. Omic provided a strong interior presence for Slovenia.

Jacob Grandinson was instrumental in Finland’s surprising run, including an upset victory over Serbia. Tyler Dorsey returned to the Greek national team, providing a scoring punch alongside Giannis Antetokounmpo. And Shane Larkin has been a cornerstone of the Turkish team for years, leading them to the EuroBasket final.

Addressing the Underlying Issues

The trend of nationalizing players often stems from limitations within the players’ countries of origin, particularly the United States, where opportunities for national team representation are limited due to the prominence of the NBA. Dual nationalities also simplify the process for clubs, easing roster restrictions.

However, concerns exist regarding players’ connection to the countries they represent. Some players, like Jaleen Smith and Mike Tobey, have admitted to limited knowledge of their adopted nations prior to obtaining citizenship.
