Vinci played very well, but when Serena beat Venus, in HER mind she HAD the Grand Slam! She wasn't worried about the rest of the draw just Venus! She wasn't prepared for what Vinci brought to the match, her shots and her movement, and now Serena's full of what-ifs!
Looking past "inferior" opponents gets a lot of players/teams beaten when they are, going in, the obvious favorite. The amazing thing is that anyone can win a Grand Slam, consecutive National Championships, or 70 or 90 games in a row.
Staying mentally prepared for each and every opponent is a challenging task. We'd all be counting on our fingers and toes the number of consecutive wins our girls would now have if it weren't for that aberration that took place last year in Palo Alto. (somebody remind me again how an opponent, any opponent, put up 88 against us).
Serena is a great champion and she will continue to dominate, but I think that RSHERMVIKES is right when he suggests that, in Serena's mind anyway, that getting past Venus appeared to be her greatest challenge.
I've been part, in my own life, as a player, parent, and fan, of too many defeats at the hands of "inferior" opponents who simply took advantage my team's state of mind and walked off with deserved, but unexpected victories.
All the more reason to celebrate a program that may (yes I said may) win their fourth straight NC.
