I've nothing particularly against you as a poster, but suggesting peak Wawa is the best player ever is either poor trolling or extreme stupidity. It was a justified bad rep and you know it
Except that it was one of my most serious threads.
One can say, Rafa, Nole, and Andy changed tennis. Hitting through their defense was almost impossible, even for the superiorly skilled Fed. They can always extend rallies so that the opponent either makes an error or leaves the court open for a winner. But Stan has beaten each of that trio in their last meetings. And he isn't a one-match wonder like Tsonga or Berdcyh, he can keep his level up for an entire tournament, AO as a proof of that.
I'm not saying average Stan is better than those, let alone better than average JesusFed. But he has an exceptionally high peak level that he can keep up through a tournament. Peak Stan might have a matchup disadvantage against JesusFed but a matchup advantage against Djokodalray, especially compared to JesusFed.
