i had the pleasure to sit courtside at pro tournaments and watch many top pros over the decades.
what i find interesting about Tipsarevic comment, is that he thinks younger pros with lower rankings hit with less net clearance/topspin. i always thought that hitting wih topspin would be one of the first things that coaches would develop in their players from a young age on. that it was a priority to learn.
