The way I see it, in basketball the two greatest players ever are Michael Jordan and Wilt Chamberlain. I like to think when it comes to guards or forward (smaller players) MJ is king, and Chamberlain is king of the big guys.
MJ is unparalleled in skill set and performance and domination compared to his peers. He had some stacked teams and of course won 6 championships.
Chamberlain broke the record books and then some. Greatest rebounder by a huge freaking distance, greatest shot blocker, probably the greatest scorer, great defender, insane strength (strongest player ever former players say), insane jumping ability (track athlete with huge vertical, see youtube for this), amazing passer (led the league in assist as a center, that's unheard of), unstoppable on offense, his only real weakness as a player is his free throw ability. They had to change the rules just to nerf him cause he was that potent of a player. Dominated the entire league, dominated Bill Russell (though Bill Russell won the war thanks to his much superior dynasty teams), and even held his own vs Kareem Abdul Jabar when the young fella was tearing up the league. Chamberlain has a lot of myth around him ( a la Lew Hoad), but looking at the footage and seeing this dude block a sky hook like it's nothing, jump up and basically put down any shot imaginable, dunk on entire offenses and just impose his will like no other, I mean how can you argue against that? He dominated every other hall of fame athlete and separated himself from the rest. Then you look at the stats and your mouth drops, those are never getting broken by anybody.
Add to that his insatiable appetite for life and his larger than life personality, I mean the dude transcended the game more so than anybody else except maybe Jordan and that's cause Jordan had the marketing/ad campaign era behind him to propel him to such status. He died when I was still too young to pay attention to sports, but from footage I've seen, this dude would have been my hero in basketball.
