It's pretty much always true when you go that far back. There are large differences in equipment, travel, medicine, even basic things like how they train certain skills, level of tactical development on the court, floor geometry as a result, etc, etc. There are large differences in rules, too. So yeah, it's pretty clear that there is a large world of difference between now and 60, 65 years ago.
That isn't to say we should disrespect the modern guys for succeeding and thriving in this environment at all, of course; there are tons of great players today, and they've adapted very well to their own environment. It's just that I think some people tire of the way the older guys are disrespected for playing the games they could play, the way they could play it, you know? And there's a lot of disrespect for and dismissal of older players, even guys who had the tools to succeed in today's game, especially if given any sort of time to train in modern methodologies/strategies, etc.
