He does have a point though.
When he entered the profession, it was a choice of dope or be spat out by your team. If you've sacrificed an education or vocational training to get there it isn't such an easy decision to make, especially when everybody around you is normalising doping, and especially also when doping (albeit less effective doping) had always been the norm for GT riders.
I think his comments are motivated by several factors. He has undoubtedly to be wary of exposing himself legally, but I suspect he may also be unwilling to be hypocritical. In a sense, given the context within which he operated, he comes out of this with more integrity than people like Landis, who's revelations were motivated purely by revenge and greed.
As for current riders? Who knows. Wiggins winning ride came straight after the Landis and Hamilton revelations and so, to an extent, he was doomed to be condemned. But he had a year of winning everything, followed by two years of sweet fa. Odd. Froome? An unlikely future winner, if viewed prior to his startling Vuelta ride of 2011.
I can't believe that riders would decide to stop doping all by themselves, en masse, without any external impetus, and I can't see that there has been any external pressure.
