Fitness and overall athleticism (agility, balance, flexibility) have never been more important than in today's game.
It is no suprise to see both Andy and Novak @ the top when they are the best athletes, a product of tennis academies churned out finest. In terms of physically and strategically.
Nadal may have the athleticism, but the natural fitness is something he has shown to be lacking.
Roddick never had the athleticism and was declining in terms of his natural fitness.
