The Hitch said:
give you credit there. Its an interesting theory and has some merit. Could explain some of his improvement, don't know if all of it.
Some follow up questions though. Did porte frome and rogers also just learn how to suffer. Also is ip really that weak? i thought it was 1 of the most painful disciplines out there and have heard it described as simply 4 minutes of pain- in contrast to.other track events where tactics play a bigger role.
Also as far as this goes
From what wiggins said himself it certainly doesn't look like he didn't bother to try. He thought he would win both the prologue and the tt in 2007 and was furious to find out vino doped as it cost him a place. He talked like he would win both tts easy if there was no doping (though ironically cadel Evans who wiggins now declares is a clean rider was one of the guys who beat him)
I don't know if it explains all of it either, like I said, this is all just speculation based on much reading about the subject.
In answer to your questions, looking at the difference between Porte's 2010 and 2011 results it looks like he may have either over trained or over raced in 2011 resulting in comparitively poor form. After the longer recovery period of the off-season he seems to have gained form again quite quickly, in fact possibly too quickly as he claimed to have actually reached peak form in February. He appeared to be putting in more miles on the front in the Dauphine than the Tour which sort of backs that up. I think given his 2010/2011 results he certainly knew how to suffer already.
Rogers and Froome, both seem to have got over an illness/parasite that was holding their performance back, there doesn't seem to be any lack of suffering in their past results. In fact the famous Froome zigzag video shows that he definitely has that one down, only beaten in my view by the feat of making it to the top of the Bola del Mundo in the Vuelta this year on a bike that had a flat for the last 1.5km and then collapsing as he passed the line. The guy is stubborn.
Froome discovering the bilharzia (I read somewhere that up to 40% of Kenyans have it, of course most of them aren't endurance athletes) and treating it and Rogers getting fit again with specific training after a period of illness doesn't seem particularly suspicious to me although I am sure it does to others. Given Rogers domestique role his strength on the key stages was impressive but not in my opinion extra-terrestrial and there were plenty of stages where he wasn't used so hard for him to recover.
Cav, again in his book, differentiates track 'hurt' from road 'suffering', because of the limited time spans. In his example he says Chris Hoy can go 110% into his reserves for 1 minute in the Kilo but ask him to go at 80% for ten minutes and he can't do it, on page 191 he is talking about Ed Clancy and Chris Hoy, and contrasting them with himself and Geraint Thomas who have, he reckons, the hunger and ability to suffer on the road. He also links it to passion and says that when you have passion the ability to suffer is automatic, so I guess he was saying in the epilogue that Brad has no passion either which would tend to cast doubt on any ego driven need to win. Cav certainly seems to separate the 'winner' mentality that he possesses from the 'performance anxiety' mentality that many of the more physically gifted athletes have, and which Brad seems to have had at times. Maybe Steve Peters really is the secret weapon, turning gifted non-'winners' into winners by reprogramming their brains
I am sure Brad did believe he could win the prologue in 2007 but this is also consistent with him finding cycling generally 'easy', if this was his first major road 'target' then he would have certainly believed he was capable of doing it if he put the work in as he'd never failed in anything he'd set his mind to and had probably put in more specific training than he ever had on the road before, though it was a country mile from the amount/sort of training they are doing now. He still isn't the best over prologue distance after all as he seems to need some distance to 'wind up' to a decent rhythm resulting in the second halves of his time trials this year being faster than the first in the main. I am not sure where he came in the main TT in 2007 and who else finished ahead of him so cannot speculate about how many at that stage were likely to be dope affected. Cadel's performance in the TT's at the Tour this year certainly seems to have been well below his usual standards going by the surprise of the commentators, so I have no problem believing a clean and on form Cadel could beat Brad at that stage of his development.
Also in 2007 Brad had that solo breakaway of 191.5km and judging by the speed he was going when the peloton swallowed him up he certainly experienced suffering that day even if it didn't help him learn that he could still win while he was doing it

This promising
almost lesson in suffering was then derailed when his team-mate was popped and he swore off the road again and headed back (mentally) to the track for 2008.
So no definitive answers, just a theory that seems to me to be consistent with the facts we have.
