Yes. Yates will be a contender as well I'd imagine, assuming he chooses to do the Giro/Vuelta again (I think they suit his style more), and it seems likely that Bernal will perhaps do likewise as well, so it will be interesting to see how he goes if given a leadership role. Dumoulin would be the favourite though, and he's young enough to wait for the Tour to open up for him, as you'd think Froome is perhaps in the final year or so of his time at the top, and Thomas isn't the youngest either, plus of course Nibali is pretty long in the tooth (assuming he's still a realistic contender). I'm not sure who else there is really. Lopez is young and been on the podium twice, but he was a long way down on Froome and Yates this year so it's far from certain that he can step up. Roglic looked very good at the Tour, but he's 29 and with very little road cycling behind him so is much more of an unknown quantity. Quintana had a poor year last year and I'm not sure he's a viable contender, whilst Porte always looks good in week-long races but falters in GT. It needs a new generation to come through really but not sure who that will be.
