I'm not sure I agree with your assessment of Serena or Monica.
Much as I love Monica Seles and want her to win all the grand slams this year, I also accept that it has been three years since she reached a grand slam semi final. Any of the top players can reach a quarter final with an easy draw but to push that little bit further is a huge step that she hasn't taken for some time. Of course, I think we all acknowledge that she is in the latter half of her career which is probably why everyone seems to have this sense of urgency when referring to her chances of winning a slam again. Her last grand slam win was six years ago and she has been injury plagued since so I think it would be fairer to say that if she starts reaching semis or finals it will have been a good year.
As for Serena, I think that she belongs in the group that will have an off year if they don't win a grand slam. When she won the US open, I think that everyone began to think that she was going to win more soon. Unfortunately, for whatever reasons, she has only played a handful of tournaments in the last couple of years. We all saw what she was still capable of at US this year, but she should have gone further at tournaments like the French open (and indeed Wimbledon when she should have beaten Capriati) - something she probably would have done if she had played more in the clay season. I understand that this year she has said that she intends to play a lot more and has committed to much more as well. Assuming she stays injury free and plays all those tournaments, if she still doesn't win a grand slam this year it will be an off year unless her sister wins them all.
