Regardless of what Armstrong has done or what he has not done, regardless of what insider information you have, true champions always take the high ground.
You are not going to “save cycling” by leveling accusations (true or not). You have the unique position of being an ambassador for the greatest sport ever. Why squander it like a mean old man?
Is proving innocence even possible – can you prove you were not enhancing your performances? I know that you cannot. So, should I begin telling everyone that the only way a human being could win a world championship without a team to support him was to be raging with steroids? Should I explain to those with a passing interest that the only way an American could become a pioneer in European pro cycling was to cheat? Must have been - seems logical to me. We would not have to discuss abnormally low standing heart rates, or the naturally occurring absence of lactic acid production, or 20,000 miles/ year in the saddle. Saying “you cheated” is so much more efficient.
At this moment of US cycling success, the constituency in Ball-Sport Nation is ripe to recognize the value of pro and amateur cycling as a respectable sport. Why do you seem intent on eroding any kind of interest by claiming that any potentially remarkable feat was accomplished, and is actually only possible, by using illegal drugs.
In the end, we Americans always tear down our champions. Be patient. Just stick to being the good guy, and let the rabble lead Armstrong towards the inevitable slaughter.
