I still have a few stages of that Giro on my DVR. Visconti broke his ribs in the first week of that Giro (if I remember correctly it was the stage Amador ended up with the leader's jersey) and became useless for the rest of it for the team and for his own ambitions. I know he broke his ribs in a crash when he was going after a stage win, just don't remember exactly which stage it was.
The stage of Cividale (the one in which Amador took the pink jersey) is the perfect manifesto of how Visconti rides, the team was fighting for the pink jersey but he went in the break for his own ambitions (stage win, KOM points), after the last climb Nieve went clear and he couldn't fight anymore for the stage but instead of waiting for the GC group and help Amador that dropped Jungels he continued to push on the flat with 20"/30" of advantage on the GC group for nothing and Valverde was forced to pull for Amador behind.
He wasn't useless for the team because of physical problems but because he's not able to work for anyone bar himself, otherwise he wouldn't have been able to go for stage wins and KOM points, go all out in the MTT and finish 13th on the GC, his best result ever in a GT.
