Before we get too fixated on the "2013 was crap" meme - let's remember he came in "only" 4th in the Tour, 6:27 behind. And didn't he crash once or twice in it also and didn't fully recover during the race? Yes, he could not keep up with Froome, Quintana or Rodriquez and edged Rom Kreuziger by only a minute. Yes, it was a bad year for him with just about no wins. But 4th in Tour? And still 3rd at the second rest day? That's only a mammoth embarrassing failure for him--not for pretty much anyone else. I just get the feeling we're all acting like he came in 50th or something.
Then there is the "he's on the downhill part of his career" meme. Well, maybe, but Nibali is just 2 years younger, and Froome is just 3 years younger. Why do we act like those guys are a totally different generation? Quintana at 8 years younger, that's a different story.
