He had a few good time trials in his Sky time, yes. But as far as I can remember he was never a really good time trialer. In the end - I used to be quite a fan, but today I think there always was a good deal of "if only" bias from my side involved, mostly "if only he could ride for himself", a feeling I have had with several riders, which I'm a bit more careful with today. One always feels that the helpers should get their chance, that they should be freed, once you see them stronger on one or two days than their leader. You often don't get to see their weaknesses, because, for instance if they have a bad time trial day you will think "there wasn't anything in it for him, so he didn't go all out" - sure, but would he actually have been really strong if he had to be? With the real leaders, you immediately see when they fail, when they have one weak day. And although teams are not god-like they usually have a reason to make one guy the leader and another one not.
