Wiggins was absolutely battering Evans uphill and in the TT in the dauphine like a month earlier.
In the TT I would agree but the mountain stages was:
Stage 2: Evans gained 8 "
Stage 3: Wiggins gained 6"
Stage 6: Wiggins gained 15"
Wiggins gained 1'06" from the TTs and was beating him in every TT they raced that year.
Kloden while bad in 2010 was good in 2009 and could have podiumed without having to work for Armstrong and would have top 5 the 08 Giro if he didn't get sick. He was also finishing close to Tony Martin in the TTs that year and the TTs in general while climbing better and even winning a sprint. Though Kloden did have more TTs raced, Evans had rode the longer ones due to CdD and TdF. He finished 30", 46", +04", 09", +01", 17", and 09" and could have got it closer or beat Tony in Tour of Basque Country if he didn't have the overall secure so started riding safe. Evans finished 31", 8", 45", 09", 1'20", and 07".
Tony while yes not working as hard as Evans after the rest day was still in the breakaway and then had to ride in the groupetto to make sure Cavendish finished on top of his duties for Cav before considering HTC was doing majority of the work by themselves.
I still think people are underestimating how that Giro affected every GC contender. That was a monster Giro and Contador was clobbering everyone at will. He was definitely stronger in 2011 compared to 2010. While racing passively, the Schlecks lost the race in the downhill and not attacking more but maybe they were complacent and underestimated how strong Evans was.
Evans was strong all year in the mountains and TT and his recovery was really good. He avoided all the bad luck for the first time in a Grand Tour I believe and learned from his past mistakes. 2007 or 2008 Evans might lose the Tour when Schleck made his long range attack or the following day with Contador and Schleck attacking.
I think only Contador riding just the Tour would have beat him. Of course contenders crashing out changes the race but Evans still most likely wins as he is a better TT then JVDB, Vino, and Gesink and maybe more consistent at the time then Wiggins and Kloden in a GT .
