Um, Bolt has veen doubted many times in the past 2 years, and he has proven those people wrong. Bolt has had rusty starts to his seasons for the few years, but still gotten his act together by this part of the year. However this year he has raced very few times and has looked incredibly rusty in all of them, like really bad. Last year at racers he ran 9.88 and flew away from the field effortlessly.This year he ran over 10 seconds and looked like he was struggling. Add that to not really having anything left to achieve to the sport and being struck by tragedy recently, and things aren't looking good for bolt. I want him to be in the best form he can be at London, and it's hard to bet against him given his track record (pun not intended), but the short remaining future of his career isn't looking good.
