Final attempt at changing people their mind.
If Pogacar has the exact same time gap after Poggio but solo. Does he motor to a win without Pidcock taking turns? I say yes. Do i believe Pogacar rather sprints against Pidcock alone even if Pidcock has stayed in his wheel after the Poggio or sprint against the chasing Peloton after letting them come back? I would say he rather sprints for the win against Pidcock. If like me you believe both of these things to be so, then it is in Pidcock interest to save his legs as much as possible. Stay in Pogacar wheel, so to have as fresh a legs as possible for the sprint.
