Joachim said:No he (possibly) tried to cover up doping. If he did try, he failed. It came out in ways he had no power to stop, despite trying.
Arguably it came out only because LA was totally out of control and thought he could get away with anything, forever. Would all this have come out if Lance had been a "nice guy" ala Indurain? If he would have hired Landis, or not narced on Tyler, if he would not have bullied so many people?
McQuack didn't "possibly try to cover up doping", he did cover up doping, successfully, and for a very long time.
