With wooden racquets? Using their current grips and stroke production, they would shank every other ball.
I find it really weird how so many on MTF are unable to grasp the simple point that radically different conditions require radically different skills. It wasn't possible to hit the ball consistently very hard with a wooden racquet. To win, you needed touch and court-craft and the ability to kill off points at the net. You did not need colossal upper-body strength because (Laver & Hoad aside) it wasn't possible to hit non-passing winners from the baseline with the technology at your disposal and you did not need to be able to run down would-be winners from the baseline because hardly anybody was able to hit them anyway. Of current top players, only Federer & Murray & conceivably Tsonga would have been able to flourish under those conditions. Of the players back then, Laver & Hoad would probably have adapted well to today's conditions because of their brilliant timing - Rosewall arguably not. But if that is a knock against Rosewall, it's a knock against Nadal & Djokovic that they would have struggled in the conditions Rosewall had to play in.
Very interesting read, I am with you on almost all accounts but I havent seen alot from Hoad to decide if he would adapt well in this era. I think you dont even have to go that far back, a player like Sampras would struggle in this era and would maybe not even be as succesfull with wooden raquets, he really was a product of his era. Mcenroe would have major problems without wooden raquets even in his peak, a player like Borg would probably be a monster in this era, much like Nadal but I dont think Nadal would be as good as Borg in his era, but I still think he would be a top player (he would be a monster on clay in any era), I really think many people underrate Nadal's talent to adapt to different circumstances.
This is all speculation ofcourse, Djokovic might be the current player who would struggle most with wooden raquets while I really cant see Rosewall doing anything special with modern raquets.
There are limits to how much a player can adapt to different circumstances, Sampras might have developped a good twohanded backhand and stayed back at the baseline in the 2000s it has been argued but I dont think he had the sets of base attributes (like speed and endurance) needed to outrally the likes of Djokovic and Rafa with modern raquets.
