I respect Linsday bcause while always had talent, she couldn't put it together. She was very out of shape and undisciplined when she first burst on the scene.
She made the choice to pull herself together, to see how good she could be. She got in shape, trained hard, and became a Slam champion despite not having he athletic skills of most top players. She morphed into a great champion and great person, a woman who was comfortable in her own skin and never made excuses.
She has always lacked drama and has gone about her tennis as a true professional, as if she were going to a 9 to 5 job. She's been humble, gracious, and forthcoming.
From a purely tennis perspective, as others said, she has incredible groundstrokes. Watching her beat Ivanovic in Miami, shows how he not only uses pace, but consistent depth to put her opponents on defense. Given how flat she hits, her stroke production is remarkable.
