Certainly it can't be JUST about winning. It would be terrible for the east and for the NBA in general to have those three guys together on the same team. I don't think they will win the chips because they won't have any OTHER good players. I think it would be a big fail.
But it's still just wrong to concentrate that much elite talent on a single team. It would be MUCH better for the league to have rivalries (like Alonzo and Tim vs. Ewing and co., or Jordan and Pippen, or Reggie and the bros...)
