Firstly - I'm not convinced that he's doped. I'm only expressing a disappointment that both he, and Team Sky have, in my opinion, gone from being clearly and undisputedly 100% clean, to getting sucked into the layers of murkyness that cloud the sport.
With regard to your point - why take 2009 as a starting point? In 2006 and 2007 until his team mate was caught doping he was a permanent fixture in the gruppeto. When it comes to drastic transformations to GC contenders he (and Froome) share some pretty disreputable company.
In 2009 when Wiggo finished fourth with Garmin it's worth noting that his DS and coach was Matt White, who was subsequently sacked from the team for sending one of their riders to a less than reputable doctor (who got a lifetime ban from the sport yesterday).
When he joined Sky he abandoned his desire for both his and his teammates blood values to be published on a monthly basis - something he said should be mandatory after his 4th place tour finish.
He also changed his stance on the riders and staff he associated with. He previously said that if there was a 1% chance of a rider or doctor or DS having been involved in PED's then they shouldn't allowed to compete (I can't find the exact quote unfortunately so am paraphrasing). Since then Sky have hired Sean Yates, Michael Barry, and now this latest Rabobank Doctor.
It's also worth pointing out that Wiggo has been pretty much crushing the field like this since Paris Nice which was nearly four months ago - it's not an Armstrongesque peaking in time for the Tour.
Anyway these points don't mean he's doped, but they do (along with the recent history of the sport) mean he has to expect to be questioned about his integrity and should be professional enough to answer his critics face to face and transparently rather some choreographed PR exercise in sports science in October when the world's press has disappeared. The 2007 Wiggins would have done that in my opinion.
I also notice that Sky's PR manager refused to allow any questions on doping at Sky's press conference yesterday. Again straight out of Bruyneel and LA's book.
You are Pull Kimmage and I claim my £5.
The article comes across as a load of bitter nonsense by a bloke with an axe to grind because he didn't get the access he wanted to Sky in 2010.
Crap rider, Crap journo.
