Different eras make statistic conversations relatively mute when discussing anyone in the top 10 if they didn't play at the same time. Statistics is a large part of what gets them in the top ten and then after that it comes down to other things outside of metrics.
There are so many things in this era that make it hard to compare any player or their statistics to the era of any of the other players. Whether it's rest, medicine, analytics, training, better understanding of health, rule changes, etc. Even pace adjusted statistics are relatively useless in the context of fifty years separation.
Oscar is arguably top 10, he's the oldest on the list and the hardest for probably anyone on the board to judge. Probably more (counting uniquely) people watch a random December game by Lebron now than saw Oscar during his entire career.
