Well, no, then probably not. If he hadnt doped, you probably wouldnt know who Lance was - pre-cancer he wasnt really all that hot.
Apart from winning the world champs and TdF stages, obviously, although he was doping then too, supposedly.
I guess we'll never know what difference the doping made, but I'm not convinced it would turn an otherwise also-ran into a 7 time winner who never really looked like losing. I suspect he'd have been the Cadel Evans of his day - close but not quite there for years until he sneaks a TdF win when no-one's looking.
It made him a stack more money than he'd have had otherwise, that's for sure.
I see Spartacus is thinking of leaving Radioshack because Bryneel's been named in the report. A bit late Fabien, I can believe (just about) that it's now possible to get to the top in cycling without doping, but don't pretend this is all news to you.
