I have been reading this thread over the past two days, and upon reflection, the only performance that really, really, is hard to believe is Chris Froome. Wiggins ... dubious, yes, but not spectacularly so. His performance was nothing like Armstrong's in the old days, remember, Armstrong would use his Postal train as a base to launch an unanswerable attack in the last few Ks, Wiggins just hugged Froome's wheel. As Nibali said in an interview, Wiggins' performances aren't really special, basically consisting of wheel-sucking his domestiques and other riders.
Reading yesterday's posts, I wasn't convinced that the evidence indicated Rogers and Porte doped to the gills. Remember, the whole climb was less than 6K. Boasson Hagen went first, for less than 1K. Big deal. Then Rogers went, and Rogers covered 1K before blowing up. Porte also covered 1K before moving to a side. To put that in perspective, these riders were asked to make tempo for one kilometer, then fall by the wayside. I do not really think this is outrageous. On the other hand, posters in this thread are correct to point out that such strategies rarely work out because supposed super-domestiques tend to underperform (witness Tejay Van Garderen dropping off the pace and failing to support Evans). So while Rogers and Porte may have been suspiciously successful, what they actually did, ride a high climbing tempo for 1 kilometer then ease off, is not suspicious.
The judgment would come from recovery time and repetition. In the Postal train, all domestiques had supernatural recovery and could come back the next day to blow up the peloton all over again. And yet we saw little sign of Rogers and Porte today. So I am not buying the team-wide domestique doping theory, not based on Rogers and Porte climbing 1K on the Tour's first climb. However, I will accept revisions to this opinion based on future events.
Froome, however, has no explanation or justification. He has no results that could justify the results he gets suddenly in GTs. His performances seem to me an insult to the intelligence of cycling fans everywhere, and I do hope team Sky see fit to send him home.
Wiggins as I say is a more complex phenomenon but I am not convinced that shifts in muscle mass on the order of 12kg in an off season cannot be accomplished without PEDs. As you all know, you must simply burn through your carbohydrate supply followed by your glycogen, burn off your fat, and your body will begin to eat its own muscle mass. Getting through the carbs and glycogen is not such a big challenge for an athlete, and at that point, it's a matter of how much fat must you burn. If your body fat is only 2-3% you can start consuming your own muscle fairly quickly and diminish your muscle mass considerably in 3 months or so. The idea that this can only be accomplished with an illegal PED is false. However I do not say that Wiggins is clean, only that I am not convinced his performances are impossible for a clean rider. What I have seen so far from Wiggins is possible clean.
Froome, though ... He needs to go away.
