It’s not Dumoulin, but his result today raises the question. Anyone want to take a stab at this? Floyd fell from 1st to 11th when he bonked. I know a lot of times a rider is 1st only because of early, flat stages and is expected to drop when the first real climb appears, but maybe we could just consider riders who are considered genuine contenders, who are in first place at some point after the mountains begin.
