Sport can be a hard taskmaster. It requires extraordinary commitment and, upon failure to comply with its demands, has no hesitation in leaving behind an individual — regardless of his or her history — in the lurch. Neglect its curriculum and the plummet is unbelievably swift. This is true of any genre. Whether you’re a heptathlon athlete, a tennis player or a cricketer, the rule etched is the same for all: take the game for granted at your own peril.
