The league has a way of anointing superstars that's based more on marketability than accomplishment. Once anointed, they get favorable treatment form the officials, get featured on the NBA web site and TV promotions, get more endorsement deals, etc.
I agree with PapaG that Blake Griffin does not have superstar accomplishments, but the NBA definitely markets him as a superstar. Every time he dunks the ball (doesn't matter if the Clippers win or lose) it's going to be all over NBA TV and nba.com. Jeez, it's just two points. We know he can dunk already. Ever since his rookie year, he's gotten extremely preferential treatment from the officials.
Paul George has already accomplished more than Blake Griffin, and seems to be the NBA's newest chosen one. Unlike Blake Griffin, George is actually improving and may truly have superstar talent to go with his superstar pedigree. He won MIP last year at the age of 22 and has improved even more this year at the age of 23. If the Pacers make the finals, especially if they win, I think George will have the credentials to match his superstar status.
