That is rubbish. Skills, tactics, and vision can certainly not be developed later. Any rational person knows that the male specimens from your fantasies (4 second 40 yard dash, 500 lbs bench press, 60 inch vertical jump) would never be able to hit a tennis ball as crisply and perfectly as Nalbandian no matter how much training they receive. Fortunately, most tennis coaches are not idiots, so they don't go around looking for grown men with huge biceps to develop into future tennis talents.
