Indeed, the claim needs to be adjusted to be correct. One of the worst recent years was 2005: https://en.wikipedia.org/wiki/Doping_at_the_Tour_de_France#2...

There, the claim is that of the top 10 finishers, all but one participant were either stripped of result in that race or failed tests/were sanctioned for doping in another race.

(The remaining participant, originally #8 Cadel Evans, was a documented client of Michele Ferrari.)

A one-off consultation prior to his road racing career to see if he the right kind of fitness for road. I don't think the association should be used to tarnish Cadel without further evidence.
