Alright where did Roglic gain huge because of his stronger team? Certainly not when the rain jacket incident happened? Other than that he dropped Roglic twice for like 30s total, got dropped once for about 12s, and got deleted in all the bonus sprints and in a time trial.
It was a Grand Tour with aobut 6 big MTFs, including the Angliru, 30km of flat ITT and most of Carapaz gains were due to a rain jacket.

Or maybe some of the difference between the 20 Vuelta and the 19 Giro was because Roglic had an actual team in one of the races.
