The trouble is, Froome needs to attack to take time on Dumoulin, but whenever he attacks he will also look like he's attacking Thomas which will make him more unpopular. If Thomas can follow Froome then that probably makes it more likely Dumoulin can jump on as well.
If Froome is to win, I can see it being from some kind of spectacular fail from Thomas, like a major crack or another crash. The former is probably unlikely given the incredible strength Sky have, but you never know, and the latter - isn't he one of the only ones in the top 10 who has stayed on his bike so far?
