Jonathan Vaughters attacks Dave Brailsford's drugs policy at Team Sky and says it is 'doomed to fail' Sky have said they have no plans to take any measures other than interviewing team members and asking them to sign the declaration, which means any dopers who lie to Brailsford are unlikely to be exposed by their own team. Since forming his Garmin-Sharp team in 2008, Vaughters has been prepared to employ past dopers, such as Britain's David Millar, but adopts a zero tolerance attitude to any staff members involved in doping activity after that date. Earlier this year Vaughters gave assurances to three of Garmin's top riders - David Zabriske, Tom Danielson and Christian Vande Velde - that their jobs would be waiting for them should they agree to give evidence to USADA and be sanctioned. All have subsequently received six-month bans from USADA. Vaughters said he has no doubt that Sky ride clean and that Bradley Wiggins is an untainted Tour de France champion but feels it may be impossible to have a team with no link at all to drug-taking. Sky have a great organisation, they have great people in that organisation that are committed to clean racing, but do some of those people potentially have a history? Of course, but that is the history of the sport. It isn't unique to the people Sky have hired. You cannot change history but you can change the direction forward and you can use the people who have encountered that history and probably didn't really like that history. By just throwing some of them to the side, you are eliminating the knowledge base of how to prevent doping, you are completely pushing it to the side, eliminating all of that experience and the emotion of people who had to live through a doping era. I am not comfortable with my own past conduct, I am very regretful for it and it hasn't been a fun thing to explain to my family, but I can't change it. I can't do anything about it but I can have a very large and meaningful impact on the lives of riders who never had to dope. I can bring guys like our young rider Andrew Talansky into an environment when they are never going to have the decision placed in front of them - and one of the biggest reasons for that is that they have got people like myself and David Millar who lived through a nasty time and are telling them and showing them the correct way, mentoring them. No rider should ever have to go through that, it is just horrible. Management has to do everything they possibly can to prevent that from occurring. That is their responsibility. I just don't see that team management's responsibility is to chase ghosts from the past.
