The last few comments have encouraged me to pop over and have a look at other sites for comedy value.
Personally, I think that Sky (as a whole) are certainly clean. I also believe Froome is clean.
It is such a shame that Sky have genuinely broken new boudaries in Pro Cycling and are having quite a few fingers pointed at it! From memory, PHarmstrong had detractors quite early on didn't he? Rumours (based on supposed facts) were flying around in earnest as soon as it was decided that running a la Dirty Bertie was not really acceptable anymore?
All Sky have to 'prove' doping is their success and the jump in performance of a couple of riders?
As far as Froome is concerned, didn't he underperform quite a bit adn was a puzzle to Sky until they figured out and sorted his medical issues? And Wiggo can hardly be accused of a sudden jump in performance when you look at his career.....
LAstly on this, reading a couple of books, inc Wiggo and some stuff from Cav, it appears that in the 'old days' Pro cyclists were almost left to themselves to train as long as they turned up for the race as told? The sheer professionalism of Sky has driven the whole sport forward in leaps and bounds.
