TT past results is not always a good predictor for future results. The main reason is that in a multi stage tour the only people giving it 100% are the rather small number of GC contenders and an roughly equal number of TT specialist. So for example when looking at Uran results the only ones that matter are those whereby he has an incentive to go full eyeballs out - in his case over the past couple of season the results are not promising.
He has been high up in the GC in a number of stage races and then comes the TT that matters he regresses. So for this poll, barring an accident or mechanical from Froome I'd say the chances of him beating him by even 0.1 of a second is close to zero. Of the GC contenders within a couple of minutes of Froome in Stage 1 they were in this order behind him - Yates, Quintana, Martin, Bardet, Aru, Uran, Landa. Looking at the final TdF parcours for the TT its clear none of them (except Uran in years gone) have every performed competitively in a TT even when GC was on the line.
That said I think the likes of Yates and Martin will surprise and will be the best of the rest and it is their performances in the TT that could decide the final podium places.
