pretty sure that they are waiting for national call choices for the Olympics. For instance João Almeida already said to Portuguese media that he would love to be in the Olympics and if so it would probably change with La Vuelta participation options.I don't know why exactly but they seem to be hesitating to put Devenyns in the team. He's not yet on the Suisse startlist either. Maybe he has some issues, or they have other plans after all.
I think Vansevenant will do the Vuelta for sure and Tour and Vuelta should be too much for him.
Cavagna will surely want to do well in the Olympics TT and focus on that.
Hm, are they waiting whether the Olympics get cancelled after all?
