As for Armstrong, the only one who really knows whether or not he's used performance-enhancing substances is himself (and maybe his team of physicians). Everything we say, hear, and read about is just speculation. So why bother arguing over something that none of us knows is 100% correct or incorrect? The man has done a lot for the sport in this country, has proven to be the best time and time again, and has overcome cancer. That's all I need to know.
