Something I wonder about these comparisons outside of skill, is also the overall increase in athleticism and the progression of athletes in general to keep pushing the boundaries.
Jordan was obviously very athletic, they didn't call him Air Jordan for nothing.
But was there anyone back then that was built like Lebron? 6'8", 250lbs, athletic af. Were there any Kevin Durants back then? 6'11" sniper that can score from any level? Were there any Russell Westbrooks?
I feel like the NBA is better overall in today's game, than it was back in the 90's, which was better than the 80's, which was better than the 70's, etc.
Look at other sports for examples. Tony Hawk was a king back in the 90's, for being the first to land a 900 in a halfpipe competition. Now 900 aint shit, you better be pulling at least a 1260.
Same with snowboarding, Shaun White hit a 1080 when he won gold back in the first Olympics that allowed snowboarding half pipe - now you have to pull multiple 1080's and at least one 1440 - just to get on the podium.
Or look at Olympic sprinters. In the 1980 Olympics, 10.25s won Gold for the 100m dash. Usain Bolt won gold in the 2008 Olympics, at 9.69s. 6 of the 8 finalist runners in the 100m final all ran sub-10 seconds.
