Re: Stupid Floyd Landis...
For one, we need to reserve judgement until Landis' "B" sample is tested. He hasn't "flunked" a drug test until then (the unfortunate AP headline proclaiming just that is incorrect). Landis' overall level of testosterone was actually lower than normal - what was out of whack was the ratio between two types of testosterone in his body - and there is a possible naturally occuring reason for this. Or, he could have used illegal enhancers. The "B" test will tell us which one it is. But until then, despite what conclusions the ridiculous media might jump to, we need to keep an open mind.
Secondly, until you are a professional athlete with things like fortune, glory, a legacy, records, and millions of dollars at stake, I don't think you can make a claim like "I would never forgive myself if I did that." It's easy to play armchair QB from our moral high horse behind a monitor or television. It's not easy to sit by as other athletes are getting the fortune and glory and passing you by just because you choose to stay clean.
Note that I am not defending or justifying cheating. There's nothing worse than a cheat. But in Landis' case, the jury's still out and I believe in giving him his due process of testing two samples.
