Even if somebody like Contador/Froome/Dumoulin was in second, they would have gained 30s to 1 min on Roglic ( Roglic was only 35s from Dumoulin). So Roglic either retains the Jersey or loses Fignon style. This was a 1 in million chance which cannot be planned for. So not RaboFail maybe some minor mistakes which every team does. Even if they were perfect, assuming Roglic did not allow Pogachar to gain time anywhere, he still would have lost(38s stage 8 +10+10=58 s < 59 s trailing).
