In a perfect world, we would be able to see if players in different eras could compete with those in the current times. Would Magic be able to play against Nash and Iverson? Would Jordan and Kobe go head to head? Who would be the more dominant center, Howard or Russell? These are all questions that we as fans like to run through our head and imagine results.
When determining a starting five, it is not due to how many championships a player has or how many awards they have received, but merely for the basketball skills that they have exhibited throughout their years of playing. Although in the long run a career is typically determined by how many championships one has, it is difficult to say that they are a bad player on the account they did not win a ring.
Also, their listed position is what puts them in that category. For example, Kobe will not be placed in the small forward position just to make the squad (because we all know who should be the shooting guard), and putting LeBron at point guard also violates the rules.
Well here you go and enjoy the greatest starting five in the history of the NBA.
