Personally i do not expect them to "unlock" his full potential this TDF. But hopefully he can get close enough that he can show he can make life hard of the two GT dominators in the future if he takes a few more steps. I don't know how close he will ever get, or if he will ever get to that level, but if he isn't able to distance himself (in a positive way) from riders as Jorgenson, Hindley, Vlasov, Almeida, Rodriguez etc... that he is being wasted on this team and that they have not nearly unlocked his full potential.
Probably because he's had his share of both misfortune as well as haters who fail to see how good he really is/can be.
