So here's my thought about morality in sports.
Athletes, great athletes and those who got close to touching greatness (even in their own heads) have a personal relationship with sports and typically feel betrayed by cheaters. It's personal because there's a sense that something may have been taken from you or someone like you because this person cheated.
Casual observers and the general public have a different relationship with sports. It's about entertainment. Lance transcended in entertaining. He made the American public and the world at large care more about cycling than they had in a long time if ever before.
For those of us who know the grind of elite athletics you know that great drama like we saw in those 7 tours doesn't really exist in non-enhanced sport - at least not drama that can be consumed by casual observers and the general public.
In a way that had never been done before, Lance transcended as an entertainer in sports. Because of that, many of us who are able to compartmentalize our feelings about sports can still see him as an icon of a hopefully ending era. Most casual observers and the general public probably feel this way.
Lance also transcended as a cheater, he personally attacked those who tried to out him and successfully battered down anyone who tried to shed light on the truth. He was so successful because he was so ruthless and he almost got away with it. This makes him less forgivable than the average cheater; but this also makes his story more compelling.
There are those out there who will always stay above the fray, and thank goodness for them, but most all of us (especially on this site) have a competitive streak and even if we wouldn't make the same decisions that Lance did we can empathize with his unique choices. His story is interesting and I am grateful I was able to observe it first hand.
I appreciate Lance for what he was and I also resent him for what he was, but god damnit I hope I'm wrong but I doubt we'll see another athlete who can do what he did for cycling for an endurance sport again in our lifetimes - and for that I thank Mr. Armstrong for the ride.
