well its better to be prepared. If you're playing a junkballer in the first round of a tourney you tend to get lazy with taking the racket back because the balls you're hitting have no pace/spin. However when you get past that junkballer and you play a seed or a hard hitter you'll have to get your racket back much faster than you would've in your previous match b/c of the introduction of pace. I'm just speaking from experience here.
