i never said he will be dropped like tony martin, in fact i have said many times that wiggins is great on those flat stages ending with a climb (verbier, arcalis, mont ventoux and pretty much every vuelta stage except the angliru) where he suffers is on mountain stages with more then 1 mountain as he simply can't itt himself mountain after mountain. and that is why i think he can't win the tour even with this many itt's, because the mountain stages even tho they are scarce are well designed (from what i remember) this year.
evans was in bad shape in 09 and menchov had just won the giro so using them as a measuring point is rather silly. Nibali himself said he completely ruined his vuelta prep last year by overestimating the effects the giro would have in him and reaching the vuelta both under trained and under raced and nibali isn't the kind of guy to make up lame excuses so i will take up his word.
and yes he was super strong at the dauphine but on the toughest stage he was very close to cracking, if that was the tour and not a prep race, guys like andy, evans, samu and nibali would have explored that weakness and crack him. Besides i think he is better at 1 week races then GT's because recuperation doesn't play such a big role.
