Rusty Shackleford
G.O.A.T.
In my opinion he is extremely good. The problem is that for S/V he needs to have an effective serve (which Rafa can do sometimes). But if he can get his serve in shape, this might be a good approach for him to shorten matches.Rafa should REALLY S&V more or 1-2 punch serve-FH combo instead of rallying so much. I don't think he realizes how good he is at it.
Nadal is naturally gifted at the net, I think. Great net coverage, awesome reflexes, superb overheads. But he was so good at counterpunching from the baseline, that he never really incorporated S&V as much into his game as he could have. It could be a smart thing to try now, at least on fast(er) surfaces.
