Who is the Greatest Server of All-time?
It's hard to judge players from different generations, but I thought this would be an interesting topic to discuss. Couple of tihngs that must be taken into account though:
-not as good racquet technology, so lower serve speed
-but this means it's also hard to block the serve with weak string/racquet, etc.
-coursts are WAY slower, so harder to ace/hit service winner
-players return much better because of racquet technology/better reflex, etc.
