I think we've all been watching sprinting long enough to get a sense when someone is doping..ask yourself honestly, does Bolt look even remotely over-muscled or bulked up? He looks like a well muscled deer bounding along, not a 'roid case. I'm not going to commit a libel against anyone but the bulging muscles on the more slightly built frames of some of the sprinters did raise some questions in my mind, but for what it's worth, Bolt looks clean.
I get a little tired of his excessive celebrating too, but I try to remember two things: First, all champions celebrate and they chose to focus on Bolt celebrating for 5 minutes before they finally got back to race analysis; Bolt probably doesnt celebrate a whole lot more than anyone else, we just are forced to watch it. Secondly, I read an interview or article of some sort where he explained that all his celebrating at the olympics was a nod to his cultural background. It may come off as unseemly to some, but I'm sure we can understand that his parameters may be a bit different.
It's hard accept that someone ran a clean 9.58 because it's like flying cars-something we were told is going to happen far off in the future, it at all. It's hard to compute that it happened today, but let's not just assume Bolt is doping, based on no evidence beyond an 'other-world record.'
Lastly, Congratulations on an excellent performance and well-run race, Tyson Gay.
