It is just impossible to keep comparing different eras in sports. In team games, you cannot just say because of this player, that player etc. Basketball is a team game. If it comes down to the blame game. Who can lebron blame? Well he can blame the superteam gsw. They are just too powerful. So i ask you, who can Bird of the celtics blame when they lost to the magic lakers? Bird was 3 time mvp, straight pa yan, and his team still lost to the lakers.
Even if lebron is the best player in the nba, it will depend on his team. Cavs still went to the finals last year. Those were not easy feats.
Jordan's bulls never had to compete with a superteam like the warriors. The closest superteam at that era for me is the 86 celtics and the 87 lakers. Jordans bulls cant even beat these teams and the bad boys of detroit. Im not taking anything away from the bulls. It is just impossible to say who is the greatest, the greatest team etc. Because the teams, players and rules are different for different eras.
