Annika does get taken for granted. I think that was one reason behind her urge to compare her game to the men's Tour. Like Tiger at his peak, she doesn't really have anything pushing her week in and week out except to see how well she can play the game. She never has to show up to a tournament figuring out a way to come out on top. If she shows up with her "A game" or even her "B+ game" she's going to either run away with it or at worst be in contention coming down the stretch.
Watching her play on TV (I've only seen her in person once for a few holes) it's hard to see just why she's so dominant. You watch Tiger when he's on and he has so many shots, pulls off so many minor miracles in the short game and has such an ability to string together the putts when he needs them that you he can beat the other guys in several different ways. Annika, OTOH, hits the ball far but not off the charts far. She doesn't have much better short game than some of the others and she is a streaky putter at best. She doesn't even come across as having totally unshakable confidence like Tiger does.
My theory is that she wins by hitting way fewer bad shots. Period. She doesn't win with her putter, she doesn't always win with her power, she's mentally tough but that's not the secret. She just mishits the ball like half as often as the other players in the field. Over 72 holes she might only hit one or two real clunkers and a handful of moderately bad shots. Her opponents just can't string together four, five, six holes in a row with every single ball struckly purely and crisply and on line.
