I think some of the greats just have the talent to race and win without PED's (besides recovery drugs).
And I'm sure there are many riders who have sacrificed potentially winning careers by not doping. Past members of the sport like Willy Voet have talked about particular riders that probably could have done a lot better if they doped.
