2016: The best sports year ever?

Lightning in Rio

Usain Bolt of Jamaica leaves the rest of the field behind in a 100-meter heat at the Rio Olympics.

Between the Zika virus, polluted bay waters, spotty attendance and a certain bad-boy American swimmer, the Summer Olympics in Rio de Janeiro had plenty of problems. But the Games themselves produced spectacular moments. When he wasn't glowering under a hood, Michael Phelps won six more medals to cement his status as the most decorated Olympian of all time. His US teammates, gymnast Simone Biles and swimmer Katie Ledecky, dazzled audiences while dominating their events. And with a smile, Jamaica's electric Usain Bolt reclaimed his title as the world's fastest man.
