How could he, if he isnt able to touch the ball on the return games??? Take a look to the 5 set between Nadal and Rosol at Wimbledon, i honestly dont know if Laver, Sampras, Mc Enroe, Federer or whoever you choose would have stopped Rosol that day. In a way mostly all the players at the top level can be unstoppable so for the same reason none of them really are
Perhaps there are stories of the great Lew Hoad who had one of the great all time serve and also had the reflexes to move in a take big serves of the rise to put it away.
And yes big servers can be problem for anyone but big returners are also a problem for anyone. Jimmy Connors, in the 1975 Wimbledon semi on fast grass against the great serve of Roscoe Tanner was able to blast winners off Tanner's high velocity serves. Some players do have the anticipation and the reflexes to handle big serves and if they have a big serve, groundies and a volley to boot, well perhaps you may have this type of player. So who is the closest to that? A lot of it is first strike tennis but often a great return like a Connors, Laver or Djokovic can neutralize a big serve.
