I think someone who gets horribly forgotten is Oscar Robertson. I never saw him play, but the guys statistics are unbelievable... go to BasketballReference.com and have a look, everyone knows about the 1 season he averaged a triple double but he almost did it like 6 times... add to that he was regularly getting 30ppg aswell, it's crazy.
You have to think of the pace though, in Oscars second year in the league, his team averaged 123.1 points a game, and they grabbed 70.8 rebounds a game. The highest rebounding team in the league today averages 44.4 rebounds a game.
Oscar was grabbing 17.7% of his teams rebounds, a guy like Lebron grabs 17.2%, in todays day if , that would be about 7.4 rebounds a game for Oscar. Then you also have to consider that he played 44.3 minutes a game.
Oscar was also said to be an extremely selfish player, he was said to hog the ball like crazy, but I like the guy. In this day he'd be a 20 points, 7 rebounds, and 8-10 assists a game player which would still land him in the HOF for sure.
A guy like KG would have averaged 22 boards a game back in the day, so just adding that when comparing stats from really long ago, think of the pace of the game. Those players now would still be stars, but guys averaging 22 rebounds would be averaging about 13-14 rebounds.
When I think of older player though, outside of Jordan, I think Bill Russell, I've read and watched a lot of stuff on him, and he impressed me more than a Wilt Chamberlain. If I was to rank the greatest players, I'd go Jordan, then Russell.
I don't think you have to win a championship to be great, but you do have to have a winning team. Many of these players had to face teams we consider dynastties right now in order to get the crown, and if their team just couldn't matchup to them, it's not their fault, but as long as they aren't averaging 30 points for their career, and their team makes the playoffs only once
