Serena´s comments seen in broader perspective
I think what is lost in the mist is that actually Serena said something really big with those comments. She basically said that on today´s tour she really needs to play her best to win, otherwise she´s gonna get burned...
Face it, there was a time that Serena could play average and still win in straights....but this year she found out that only your best play, either mentally or physically, will be good enough.
So for her it was encouraging to find out that on a day that her forehand was almost always finding the net and that she couldn´t win most of the long rallies, that she still found out a way to win. THAT is what I think she was talking about.
