By Julia Love and Rory Carroll OAKLAND, Calif. - International talent has turned from novelty to necessity in the National Basketball Association and that shift was on display in Monday's clash between two of the league's best teams. When the defending champion and league-leading Golden State Warriors hosted the San Antonio Spurs, the game featured players from seven countries. The Warriors, aided by centers Andrew Bogut of Australia and Festus Ezeli of Nigeria, cruised to a lopsided 120-90 win over a Spurs squad that includes French point guard Tony Parker and Argentine veteran guard Manu Ginobili.
