6. Manu Ginobili
Given that he's played professionally since 1995, Ginobili should be an old 35. But the smooth Argentine has averaged 66.7 games per season over his career, and his per-36-minute averages last season (20 points, 6.9 assists, 5.3 rebounds) suggest he isn't really slowing down. He won't match the $14.1 million he's scheduled to make next season in his next deal, but he seems like he has one more multiyear deal left in him.
