Wilt is the best, Kareem 2nd.
If Wilt didn't have to play Boston every year which was beyond GS stacked, he would have more titles. The guy averaged 50 points a game. Then he led the league in assists. They didn't track blocks back then, but one game, an assistant coach decided to track it and stopped in the 3rd quarter when he had 27. Wilt had a 48 inch vertical. He ran the 220 hurdles at Kansas. He was also a high jumper. In his late 40's, he was considered the best volleyball player on the planet. Arnold challenged Wilt in the bench press when they were shooting one of the Conan movies. Wilt made it past 500 pounds on the bench press and they decided to stop.
Statistically, Wilt was superior. Athletically, he would be a freak even by today's standards.
