Usain Bolt set the world on fire back in 2009 smashing the 100 mtr and 200mtr world records. Since then though his times have dropped massively, in 2014 he barely broke the 10 second barrier for the 100 mtr's. Most of his fellow countrymen have been busted for taking banned substances and the entire board of the Jamaican Anti-Doping Commission resigned. Bolt swears he is a clean athlete. Is this a case of an athlete reaching his peak in 09 and naturally deteriorating or were more sinister forces at work?
