"The guy can't win at Worlds".
He was 3rd in the WC 100m final but it was pretty clear he tightened up and gave up when he realised that Tyson had beaten him. Hardly the biggest choker ever, he still has a bronze in the 100m world champs and performed well in the heats.
"The guy is on something".
While I will never claim to know whether someone is guilty or innocent until proven otherwise, this performance was not that far removed from what he has run before, especially considering the conditions were probably ideal for him - relaxed , slightly high altitude , small meet etc.
"The wind gauge was broken"
Well I am sure the iaaf will not ratify the record if that is the case.
I have no more reason to cry foul on this than on any other performances by sprinters this year. I suspect its just a case of your pick not getting it first.
