Regardless of whether or not one thinks it's the truth, the press line ever since Garmin started was 'we have a team that wants to make people feel comfortable that they can be here without doping'. It stands to reason that riders who previously doped but were uncomfortable about it would be interested on being on that team. You can choose not to believe it, that's fine, but it's simplistic to paint all dopers with the same brush - people do it for varying reasons and have varying degrees of comfortability with it.
I do happen to be cautiously optimistic that JV's statements about his own team, at least, have some truth to them. I'm personally not sure how it would benefit Klier to lie about stopping in 2006, since there seems to be no real incentive for him to confess in the first place (and, in fact, a disincentive in the form of a suspension) other than telling the truth and adding to USADAs knowledge of what happened in that time. Do people think that there's some kind of layered omerta, like they're circling the wagons tighter? JV saying 'okay guys, we've gotta tell 'em we doped, it'd be insulting their intelligence not to... but let's at least lie by all saying we stopped in 2006'? I'm curious what people think, actually, because all I really read are 'yeah, whatever' sarcastic comments without explanation to counter the simplest one, that they're telling the truth.
