The others can do that as well, they are just choosing to stay put. I don't see what makes them interesting to watch. Tom Dumoulin for instance is a lot more fun to watch for instance and if it wasn't for the stupid world tour points system, you'd that type of people more. As for Aru, he is a good example: why is he so scared to race? Froome is not going to get him back if he doesn't need to.It is easy to say how amazing it is to watch Zakarin win a stage. He is 40 minutes down and can pick and choose when to go.
Aru proved in the the Alps of Italy two years ago what an exciting climber he is and can blow a field away. However, going up against Tinkoff and going up against Sky are two different beasts.
I really hope that Aru can keep it respectable in today's TT because I really expect him to make a strong push for the podium. Anything less will be a huge disappointment for him and Astana.
I do agree that there are too many riders just happy for a top 10 spot. The only team that has really tried to push Sky is Astana, but this has been their worst GT in awhile. Maybe it is no surprise when the two richest teams are Sky and Astana.
With Teejay now out of the GC, hopefully BMC can get at least one good stage out of the team. Caruso,GVA, and TVG really need to put in a shift for Porte.
