That's rubbish. Armstrong had already won the world RR champs in 93, so was hardly 'unknown' - and another bloke called Lemond had already won three TDF titles - it's possible the Yanks may have noticed that. It might not have been major league baseball, but it was not 'fringe' either....
I'm not sure it's rubbish. Armstrong had already won the rainbow thingummy, but was little known in the US beyond his own family and the domestic road racing and triathlon communities.
Lemond, too, was not a widely recognised figure in the US.
Even in Europe, Armstrong was not too well known before he got his first TdF win. I followed cycling back then and was aware that a yank had won the World Champs and the odd TdF stage. Could I name him? Could most people?
There will always be people who come on and say that they had him marked down as a future multiple TdF winner as soon as he stopped doing Triathlon, or as soon as he got a stage in the Tour... Before he got sick, he was one of very many fast, young riders who looked as though they might have an impact.
I've spent quite a while working in the US and do not recall overhearing a conversation about pro cycling. I overheard 38,486,000 chats about sport: NBA, Football and Baseball. None about pro cycling or the Tour.
I imagine most US citizens still know little about Lemond. What is known about Lance Armstrong is sometimes clouded by strongly partisan views and unusual reporting in the domestic media.
Armstrong (the man, the brand, the survivor et al) has become a phenomenon and a divider of opinion since his first few consecutive TdF wins. Had you asked anyone in Europe or the US to name 20 pro cyclists at any time pre-1999, almost nobody would have got past five names and none of those would have been Lance Armstrong. In the US, few people outside cycling would have got past two names.
You can argue that LA was hardly an 'unknown' in '93, but he was very close to that even in Europe and absolutely that in the US.
