I've gone to a few Pro Tennis Tournaments, and I'm always struck by how nonchalant many of the pros practice. I certainly do not question the work ethic of a pro tennis player because I'm sure they put in hours upon hours of work. In addition, I'm guessing that they often want to "save their legs" for the real matches. That's why you'll see sloppy footwork perhaps. Also, I'm guessing that playing these tournaments can be extremely stressful. To get out on the court & goof around a bit maybe relieves some of the stress. Agree/Disagree?
