Since he coasted to the 100-meter finish line in world-record time at the Bird's Nest eight years ago, Usain Bolt has been the smiling face of track and field. He has served as the anchorman of the Olympics — virtually the only reason any casual fan would pay attention to a sport that has orchestrated its own slow, sad, drug-infused downfall.
His tender hamstring improving, Bolt will be back for a final go-round at Olympic glory when track starts in Rio de Janeiro on Aug. 12. If, as expected, the Jamaican wins all three sprint events — the 100, 200 and 4x100 relay — he'll only add to his legacy and cement himself at the fore of any conversation about Greatest Olympian Ever.
