Drugs or not, I think this year has been a great year. Ok Nibbles (Froome and Contador would have had a run for their money*) grabbed the lead early, but he continued to attack. Then there is the fight for the two other steps. Great to see so many young riders coming up. Oh and a French person on one of the steps. The green jersey I think needs to be rewritten, it feels not right that you can "win" that in the second week and with that much difference. The polka dot, is still interesting, though some years a bit boring. The white one I enjoy watching.
Young riders like Quintana, Pinot etc coming up, I think the next few years will be great for cycling. Lets hope they are not just "proving" themselves with all the attacks and when they get the big deals they go back to the "old school" ways of controlling the race.
* I so hoped that Quintana would have been in this year
