Possibly, but I've been watching track for decades and virtually every one of the top sprinters on the all time list has either been banned for doping or it was found out later that they'd gotten away with doping. I can't believe that Bolt was the one guy who was far better than all of them and he was clean. Sprinting is so dirty that I believe they're all doping, so Bolt is the best anyway and to enjoy it you have to stop caring that they're doped.
