I really do not think that Nibali would have been anyway near Froome or Contador in this Tour if they were still in it. He hasn't impressed me in the sense that the main contenders he is taking 'some' time on are some good French climbers, Valverde and TJVG.
His victories in most GT's have been against developing riders or riders who are well past their best imo.
