I've heard a lot of innuendo around Sean Yates, just wondering how long he was working with Lance (that article suggests only one season, one Tour de France).
There's an easy assumption to say he's the DS, he must either know or worst be complicit in the doping. However it's clear he wasn't a major protagonist in the doping (of Lance and the rest of the team), like Ferrari was, even if he was aware of it. While he's quilty of sticking to the omerta (and there aren't many in the sport that aren't), it's not as if he was supplying or instructing the riders in the use of EPO. That would seem to be the domain of Ferrari and Lance himself.
I also thinks it's a fallacy to suggest manager/bosses etc are aware of what their employees are up to. I'm an account manager so essentially sales, so know that people will take an opportunity to achieve targets, sometimes by foul means if the necessity is required. I've never fully broken rules, but I have skimmed them on occasion. You know what? Success armours you: a company isn't going to conduct witch hunts on their best achieving employees. Sean Yates comes into the TdF as DS of Lance Armstrong in 2005, where is the power?
If you think with Yates you are in cloud cuckoo land. Lance called the shots, his influence clearly extended beyond the team, throughout the peloton and into the sport's governing body. You think if Yates had said anything, anything would have changed? He would have lost his job, he would have been black-marked and out the sport. And while he may have suspected as everyone did, I doubt he was in the inner-circle.
Just remember managers don't always know what is going on: that's why get rogue-traders bankrupting banks. Also remember in companies or teams managers or captains can be less influential then the successful members of the team: even if they call a person on their performance the chances are nothing would change.
There is a danger of being overly puritanical: the sport was riddled with drugs, it's impossible to emerge from that entirely untainted. Yates may have turned a blind eye, but he wasn't a major protagonist of the cheating either. I know the fevered desire to build team Sky into a zerox of USPostal, but Yates isn't the conduit IMO
