I have an ongoing debate with a tennis friend about whether Lance Armstrong took PEDs, engaged in blood doping, etc. In a nutshell, he says no, he won't believe it until he tests positive or there is a "smoking gun." He argues the accusations are just "sour grapes" and that no one ever accused Wilt Chamberlain, Michael Jordan or even Roger Federer a few years ago of using steroids or PEDs in general despite each dominating his sport. (A terrible comparison, I might add, since basketball and tennis are more a game of skill while cycling is almost purely an endurance sport.) I say you would have to be INCREDIBLY naive to think Armstrong didn't use PEDs and that it was extremely unlikely that a clean cyclist would dominate a sport where drug doping was rampant. So, simply put, do you think he did or didn't?
