Froome is a far superior climber to Dumoulin, especially in the third week of a GT. A lot of pundits seem to have forgotten that Dumoulin shed the best part of 4 minutes to the likes of Pinot, Quintana and Nibali in the final week last year, although he had a time trial as a buffer as the final stage so could afford to lose some time. He doesn't have that luxury this year.
