He seems to have got to a level and is maintaining it IMHO.
He's doing it roughly the same way as Bradley did it last year, peaking at the TdF.
With Dave Brailsford but especially Tim Kerrison there will be nothing left to chance and I fully expect him to be in yellow on the Champs Elysees on 21 July for what will be a fantastic evening climax.
I'd like to see Chris Froome at least be given the chance this year -- feels like it ought to be "his turn".

He will and it is. He is pretty much the confirmed Team Leader for the Tour. There is a suggestion that Bradley will get just as much support in the first week, just in case Froome suffers a race-halting crash etc but the route favours him anyway, Bradley knows that, hence his focus this year is the Giro.
