Very well stated, and a good example because by isolating it
down to a specific case, "When a player serves to Goico in
singles and its a good serve putting Goico in the corner"
it wouldn't be too tough to find similar cases from videos from
yesteryear to make a very clear A-B comparison.p
And it's especially important in singles for the bigger, more
powerful players because they can pass even from extremely deep
in the court. Therefore it is often the case that the only practical
chance for their opponent to get control of the point is with
a beautifully placed deep serve. And as you said, negating that
is just not right.
