This week, we unpack one of the great sports ads of the past decade, Droga5's Michael Phelps spot for Under Armour, made for the 2016 Olympics. We look at how the spot shed new light on the world's greatest swimmer, how it was expertly concepted and crafted, and how it was ahead of its time in broaching the difficult subject of Olympic athletes and mental health.
