Have to agree, Chaves without either of the Yates to support him/take over is a bit of a hindsight as I think he'll struggle to be an outright leader and real GC contender. Equally I want to see him nail a few stages, but don't think he quite has it (yet) for a GC tour win. Although he's young, so I'm convinced he has the pedigree for it to come sometime!
They could've put 1 of the twins in the Giro as leader, the other in the Vuelta as leader and Chaves in the tour. Then the others acting as leutenants for those they're not leading, so they could support each other. Not many teams have 3 real GC contention climbers, so they should've used that to their strength!
Ref: Underdog. All 3 of them will always be underdogs!
I think being seen as an 'underdog' is how Adam did so well in the tour last year, Chaves seemed to be marked more.
