All that being said, games evolve. The fact that we don’t adjust stats to make them relative to the era is stupid. You should and your dominance should only be compared to your peers and the normalized. WiS already does it in baseball and there are already sites that do things like adjusting FG% by era. It would make old guys so much more useful in the sim and be in the spirit of the website.
They say they already do that with fg%#, but they either a) don't or b) don't have the right formula in for fg%# because it's nowhere close to what it's supposed to be. I lean toward B. For example, if the league average was 42% shooting, and a guy shot 46.2% from the floor, that should be a fg# of 110. Once you determine the modern average fg% (was 46% this year)... the player's fg%# should be 10% higher than that, or 50.6%. But wis claims to go beyond that and inject average defender (which is LOL when you consider their defensive ratings and how they are achieved) into the mix, which makes fg%# almost unnoticeable. Rare exceptions exist like Wilt who almost always shoots well beyond his normal fg%, no matter if you're using the late great support Wilts or one of the Wiltzilla-esque seasons.
In regards to the old athletes vs today... that was what they had. I am in the camp that believes that if you give the athlete of the 50s (or 60s, or whatever decade) the advancements in nutrition and physical development that we have today (not to mention the emphasis placed on those things in today's world that didn't exist back then) that they would be of a similar athletic state to today's athlete, and those who were godlike then would be even more godlike now. Guys like Russell & Wilt would be in Lebron-type shape. By the same token, if you take today's athlete and put them into that old era where they didn't have access to the same type of advances and sports (nba in particular) wasn't a multi-billion a year industry where people world wide are obsessed about it... those guys probably wouldn't be much more athletic than those who played. Your ridiculously gifted guys, sure, would be ridiculously gifted then - like Wilt & Russell were.
There's also some pretty significant hurdles many of yesterday's players had to climb that today's players don't. Yeah, racism still exists in a big way, but there's no comparison to pre-civil rights movement. 80% of today's players would never even sniff the pros just because they are either African-American or not American at all.
The rules are different. Hell, the rules are different from 20 years ago. They're different from five years ago.
There are so many factors at play that it's almost an absurd conversation to have. At the end of the day, my stance is that great players would have been great in any era. To say otherwise is really just disrespectful of the players and the game they play IMO.
Oh and the dribbling thing has a lot to do with how the game was called... again, rules difference. Ball had to touch the floor for every step you took. If you dribbled anywhere but on top, it was a carry. These things evolved - especially during the 70s & ABA, I think - into a game that appears almost entirely different.
