While everyone knows about Manu Ginobili's outstanding career in the NBA, he also had a wildly successful run in Europe prior to coming to the United States and joining the Spurs at age 25. While he was drafted by the Spurs in 1999, he returned to Italy and promptly led Kinder Bologna to the 2001 Italian Championship, the 2001 Euroleague title, and the 2001 and 2002 Italian Cup. Manu was outstanding in those competitions, winning the MVP of the Italian League in both 2000-01 and 2001-02.
He is now generally regarded as the blueprint for NBA teams drafting foreign players and then letting them develop overseas before bringing them to the US. Considering Manu's incredible success, it's hard to argue with that tactic.
