I know eventually someone will tout every team in the poll, but Movistar could potentally score a lot. Valverde's back, Visconti's a grafter with a finish, and the teams just deep: lots of guys that can win given the opportunity.

1. [Usa] HTC - Highroad PRT 56
2. [Iri] Tabriz Petrochemical Cycling Team CONT 35
3. [Usa] Team RadioShack PRT 33

Actually, looking at that, Movistar won't make any waves, and Lotto with the combination of Greipel and Sohrabi might be unstoppable. Sohrabi is unproven in the WT, obv.
