I want to say Dirk Nowitzki. No doubt his consistency year in and year out will be hard to stack up against.
I seriously hate the guy, but if we were talking about foreign-born player I'd have to throw Manu Ginobili and Tim Duncan in the mix. Ginobili might go down as the most awkward player in NBA history, but as much as I hate his style of bb, he is a winner. He also has an Olympic gold medal from 2004. He is a driving force in San Antonio's drive towards the best record in basketball nearly every season (along with Tony Parker and Duncan).
