That's the main difference between you and us sir, our viewpoint isn't just NBA-focused. Not to mention that they are vastly different players, in terms of playing positions. However, of course I respect your opinion even though I kindly disagree.
They did play different positions, but when you rank one above the other, I have to consider that you are comparing the player overall. Galis may have dominated European ball in the late 70's/80's, but Dirk has been dominant in the NBA during a time when foreign players are prevalent. Dirk has shown he can do it against the best in the world. Galis has questions, in my mind.
