Becoming a Nibali fan now would be like becoming a Contador fan in April 2015? Well guess what, I became a Contador fan in 2016
Anyway, there are a few riders in this list I'll root for. I like Dumoulin but I think as soon as another really aggressive climber who doesn't depend on his TT rides against him I'd rather root for the climber since he is probably more entertaining to watch. Therefore I'll mainly root for Nibali (although I've been a big Nibali fan for way longer than I've been a Contador fan), Landa (because the guy attacks and isn't afraid of attacking from far out) and Mas for the future, although I fear he won't be tdf winner material,
but rather a typical top ten finisher who might get a podium or even a win, but will most likely not be the next dominator, considering other riders his age look more talented.
