If I had to pick a center for my all time team, it would be Abdul-Jabbar for sure. He was an absolute weapon. I would then start Bill Russell as my power forward along with Bird, Jordan, and Magic. Good old fashioned tall ball, size at every position.
Now if you were to make a team of Robertson, Kobe, James, Malone (Karl), and Wilt, and try to make the case that is was just as good if not better, it would be a hard argument to settle.
