Simply put Lavers accomplishment is way above what peeps think, no hawk eye, grass courts where the ball bounce was unpredictable,wet surfaces,ect.
His style of play is not used any more,, his volleys were mostly to the center court , struck so that the bounce was below the net and dying in the opps service courts, then he came forward and challenged the opponent,, mano to mano to volleys for the point,
bascially he was fearless.
I seen all of his matches on PBS with Pub Collins calling the play by play, he has all the tools in spades. Mr. Pancho Gonzales thats an interesting life story he was fearless also, there are others as well.
