"Oscar Pistorius is on the cusp of a paradigm shift in which disability becomes ability, disadvantage becomes advantage. Yet we mustn't lose sight of what makes an athlete great. It's too easy to credit Pistorius' success to technology. Through birth or circumstance, some are given certain gifts, but it's what one does with those gifts, the hours devoted to training, the desire to be the best, that is at the true heart of a champion."
