While I disagree with Tejano's thesis, I also disagree with this statement. IMO, the Armstrong phenomenon has certainly brought a lot of attention to the sport of cycling by "bandwagoners", many of whom will return to watching other sports when the TdF is no longer dominated by the American superstar. Then again, I'm just a clueless American myself, who was initially captivated by cycling when LeMond broke through in the 80s. While he was the reason I was initially drawn to the sport, when he left my interest in it did not diminish.
I confess that I'm not particularly captivated by the classics, which seem to be so much more important to many longstanding cycling fans. There's something about the dynamics and strategies involved in grinding out a long 3-week tour, whether it be in Spain, France, or Italy, that makes the sport so interesting to me. But the fact is, if there had been no LeMond, I doubt whether I'd have ever paid attention to cycling for long enough to know how wonderful the sport is, no matter who is riding. Whereas certainly there are many who believe themselves to be cycling fans who don't know their palmares from their peletons, I believe that there are many people like me, who have been drawn to the sport because of a particular star, who will be cycling fans forever.
In addition, I don't think anyone on this forum has a truly "objective" opinion. Certainly, Tejano's views are a bit over-the-top, but everyone in here has demonstrated that they have some level of subjective bias. Wishing all the Disco fans to "go away" because you disagree with them, for example, is a bit revealing. I confess I'm rooting for Armstrong to win again this year, because although by all accounts he can be a real *******, I admire the tenacity and determination with which he has dominated the race he points to every year. (Although as I've said, I hope it's close between him and Ullrich, because I want to be treated to just one more titanic duel between the two of them.)
As for the topic, I don't think there's any way to convincingly argue that Armstrong is the greatest cyclist ever. He is very arguably, however, the greatest TdF rider in history. As far as individual cycling achievements is concerned, every rider in the world would want to win the TdF GC title more than any other competition. And Armstrong has managed it more times than anyone. To argue against him, you have to start dwelling in minutia like stage wins and polka-dot jerseys. I could be wrong, but my guess is that Virenque would trade very one of his mountain jerseys for just one GC title, because he knows as well as anyone that history is not measured in points, but in time.
