Wasn't necessarily saying Froome would have won it, but he did make it quite clear that uphill he was strongerand froome still wouldn't have won the tour in 2012 cause wiggo destroyed them all in the time trial............
The team behind Wiggo was superstrong...still think porte would be a good bet, if the team behind him, is as good as the team was behind froome and wiggins
the team behind Froome... not so very strong in my small opinion: more than once he was too isolated way too early (like on the 3rd or 2nd last climb) with only about 2 or 3 guys. I believe he actually had to ride that 1 stage about 75% alone, since all of his team were dropped.
As @Hont correctly points out ... the double is superthough nowadays. Of course he could loose (for whatever reason) too much time in the first week of the Giro and not go 100% in the Giro, but then still I would put a Porte in top-form and as a team-leader in the top 10, but I can't see him beating either Froome (in an imaginary other team) or Nibali across a 3-week race. He hasn't shown a great result yet in those 3-week races and has to do so before I put him even ahead of people like JVDB and Mollema. (Considering that they would also be in top-form and avoiding falls)
Actually Sagan takes most points away in (an) intermediate mountain stage(s), where he has his team ride so hard that all pure sprinters fall off. If he ends 1st (or even 2nd) he takes so many points with the other sprinters not taking anything. That is what makes him the favourite for Green (and not necessarily Kittel, who might be the biggest threat at the finish-line for Cav)As regards to Cav - he has every chance - the train is complete & only Kittel/Shimano stand in his way - he does need those intermediate sprint points though that have served Sagan so well.
Have you seen the predictions/statements all of us make here... no one is an expert here that knows how anything is going to happen before it doesI do not profess to be any kind of expert
