But I want to give some props to Lionel Birnie & co. at Cycle Sport for a rather thorough and cogent analysis in this month's mag of why the Discovery Channel/Tailwind folks really decided to pull up the stakes and get on with B-school or starting blogs or whatever "pursuing other interests" is supposed to mean. As I understood it, the official position was that they could have continued but for unexplained reasons decided not to. Obviously nobody believed that, and the real reasons were assumed to be lack of sponsors or something about doping.
The real truth now seems like a complexity of all of the above, and goes something like this:
There's an interview with Sean Yates where he admits as much, as well as a clip of Bruyneel saying the same thing to a Belgian paper, despite the official position that sponsors were waiting in the wings. But even still, there's room for elaboration: they couldn't find a sponsor before the date in August where the Tailwind guys got fed up with/exhausted from all the bullshit (in their eyes), so they gave up.
Part of the disconnect seems to be that Discovery feel unfairly singled out... and in Cycling, singling out anyone from the last decade is kind of silly. That said, one cannot understate the fallout from the Basso affair: Bruyneel supposedly spoke loudly for Basso's exclusion from the 2006 Tour based on the Operacion Puerto link... but then, at the earliest opportunity, signed him on as their grand tour captain. Discovery argue that there's no sin in trying to win, but such rank opportunism turned out to be really bad for business in the end. More than the hypocrisy, Discovery broke ranks with teams trying to send a very different message at that time... this may actually be what hurt their fellow teams and riders most of all.
Anyway, it's all a good read and I tip my cap to them for good, canny journalism.
