Are you talking about Vaughters??? If so, this is a completely ridiculous assertion which you have no evidence and proof of. Since JV posts on this forum, I think many would take exception of this out of line accusation.
JV has said previously, when they are looking at riders, they give them a time/date to be on a plane in a moments notice, must fly right to where they are, and when they get off the plane, they are tested. Does that mean they are clean and haven't doped? Of course not, but they get them at their height of performance/training, not when it is Thanksgiving weekend dinner when they do this. Surely a method to that madness to catch people off guard. If you have nothing to hide, then you will be there, major tour teams don't come knocking on your door, so you better be there, or something is wrong with the person.
If they are "late" to catch the plane, no-show, he claims they won't ever talk or sign them ever. They probably have one of the toughest contracts to ride under regarding doping and zero tolerance now. They do their own internal testing and such, we have no clue whether Sky has any program or testing like Garmin does in effect, doubtful. If they do, they don't like to talk about it, which would be to their benefit. A contract clause doens't mean anything though in the end, never stopped guys from doping of course.
JV has shown that he is all for giving guys a chance to race clean, even with a past/history of doping, he doesn't hide this. That is obvious by the guys on Garmin now and who have raced, which he knew before this entire downfall of LA and USADA, they doped. He kept it under wraps for the right time and really was an important piece of kicking off this entire doping issue in cycling the past year.
Shoot man, he came on the forum here and leaked about his own guys history of doping!!! Danielson, DaveZ etc...and hinted at the USADA issue and their part to help his guys stay in cycling and compete, for coming clean with their history. What other team has done this?!?! None.
Get serious man.
