Modern racquets are night and day compared to the Donnay Allwoods and Kramer Pro Staffs those boys played. The wood racquets were limiting much in the same way hickory shafts limited Bobby Jones or earlier race cars limited AJ Foyt or Roger Maris was limited without steroids. If Borg and Mac grew up playing with modern racquets, their games would have more pop. The average player on the pro tour now is just better than they were years ago. . Better conditioned, stronger, a bit faster perhaps and they hit the ball a lot harder because today's racquets allow for that... and the game has accordingly evolved to a higher level.
I disagree.
I don't think that today's players are better, or that the game is better today.
The players are different, and the game is different, that's all.
There is more power today - no-one can question that. There is more spin today. Both these elements are due to the larger, stiffer raquets. But does this mean that it's better? I think not.
20 and 30 years ago, there was less power and less spin. But there was more
thinking. There were more volleys. More drop shots. More angles. More strategy. More working the point. More dimensions to the game than there are today.
So how can today be considered better?
Is a faster car always better than a slower car? An open wheeled dragster is very fast. But only for a short distance. And it can't turn.
So, for a trip to the store, or for taking the family on vacation, a much slower car that can travel longer distances than a dragster, and can turn left and right, is much better.
It all depends on one's personal preference.
