If we're being serious here I'll say (again) the man definitely has endurance qualities. He's still an athlete, he can still complete bike races. When there's a tempo, he can usually follow. Yesterday's moderately sustained tempo by UAE over those cat 3 climbs (very generously labelled cat 3 as well, considering the gradients & lengths) suited Froome.
But whenever there's a real change of pace on a climb, he'll get dropped. Whether this happens at kilometre zero or 7km from the finish, on a cat1 or cat 4, it'll happen anyway because he can't cope with the accelerations.
This will make winning a stage very, very unlikely. This is the TdF, i.e. the stages he will most likely target (rolling or mountains), will always also be targets for riders who're better than him at racing their bikes over all terrains & profiles. Whether they're stage hunters from a breakaway or the GC favorites.
He's good enough to complete the TdF, not good enough to race for wins or really make an impact.
