Well, we will probably have to agree to disagree, but if Dan Martin had 1 race day where he won Lombardia, I would still think he had a better season than Valverde. I really do think that Kristoff, Cancellara, Terpstra, Gerrans, Quintana, Nibali, Contador, Kwiatkowski and Dan Martin had better seasons than Valverde, by merit of actually winning a really big race. I also think that Valverde's seasons with LBL wins and the Vuelta win are better than his season this year. But it's a different way of thinking I guess, I doubt whether a discussion about this would be very fruitful.
By the way, I can understand how you can think can think Valverde had a better season than Dan Martin or Terpstra this year, though I strongly disagree, but I can't understand how Valverde can think this season was better than 2006 (FW, LBL, 2nd Vuelta + stage, 3rd WC), 2008 (LBL, Dauphine, San Sebastian, Vuelta stage, TDF 2 stages) or 2009 (Vuelta, Dauphine, Catalunya). When I read a statement like in this interview, I am a bit annoyed by how little value he seems to attach to actually winning compared to how much value he seems to attach to getting 2nd or 3rd.
