The point of this is to look back and compare with today, and wonder- could a grand slam draw open up sometime in the future and we end up with a Tipsarevic, or a Wawrinka or anyone taking advantage and picking up a shock slam or are those days long gone? Stan almost defeated Nole after all...
Sorry, but no.
The courts are simply too slow for guys like Djokovic to be defeated by someone like Stanislas, even though the former is playing lights out best-of-his-career tennis and thoroughly out playing the latter; it's disgusting and disgraceful but it is what it is.
Djokovic will always be able to grind and grind and grind his opponents down until the courts are sped up (if they ever are).
