"It is generally agreed that playing soccer is a good crossover skill for playing tennis, because of the footwork."
Generally agreed? I've never heard this before.
Soccer is one of those sports where I'd like to get better but lack the patience to build skills consistently.
If you want to learn how to dribble a soccer ball, do it in the edge of the surf beachside. The water resistance makes it extremely difficult. Get a small soccer ball called a skills ball. Soccer or (football) is one of the sports where footwork can make you a valuable team player. Speaking of which, less than one month to World Cup 2010!! (June 11th)
