I think Hoad would have handled Nadal's lefty topspin forehand. He liked to take balls on the rise, and hit winners off of them (a la Wawrinka).
You are correct about Laver: he would not have stayed back and tried to rally with Nadal. He would do that for a while, but would look for any opportunity to come in to the net to end the point with a volley (a la Panatta v. Borg).
You fans of the old players like to think this and that, but Wawrinka has only one win on clay versus Nadal and that was last year when Nadal's game was in gutter.
As far as Laver goes he would have been passed a lot.
It's much easier said that done.
