Kareem's argument is weak and passive in that he is arguing in favor of Wilt in order to build himself up. Kareem did not even like Wilt Chamberlain and has called him a "crybaby" etc in the past. Kareem is mad that people never really mention him in the greatest of all time discussion and he is just stirring up some shit.
If rings mean everything then Robert Horry is better than Jordan, Barkley, Karl Malone, Lebron, etc.
And the all time leading scorer title loses a lot of its luster when you consider that Kareem played until he was like 41 years old. If Jordan would have played as long as Kareem he would be way ahead of him on the all time scoring list.
The 50's- 60's NBA was slow and teams shot horrible field goal percentages, most teams shot right under 40% from the field. It was a field day for big men especially exceptionally talented ones like Wilt and Russel to put up those crazy rebounding numbers.
Kareem never averaged 30 or more points a game after the 75 season and his numbers went down every year after that. This was way before Magic came to the Lakers,Kareem was still taking most of the shots and was in his physical prime.
His drop off was due to the fact that the NBA changed a lot in the mid 70's after the merger with the ABA. The merger expanded the league, introduced new talent and sped up the pace of the game. Before the merger beasts like Moses Malone, Julius Erving, George Gervin and David Thompson were not even playing in the NBA.
The three point line, slam dunk contest etc. the merger permanently changed the NBA style of play. Kareem was there to see the newer era and also saw his dominant stats he had in his early Milwaukee years drop off. Kareem was a great player but he more than likely would not have dominated like he did in this era or Jordan's era.
