Man, if Quintana could TT he would be so much more of a stage race contender (dominator?)

Why is it that he is such an average TT rider and such a great climber? You'd think with his great power-to-weight combo he ought to be at least decent in TTs. I realize there are other factors but I can't think of any other pro cyclist who has such an extreme mix of great climber and mediocre TT'er.

Today he just gave away everything he won on the big climb and then some.
