Caleb has got a hell of a long way to match Cav, and now Orica has developed GC ambitions he'll get less support. HTC-Highroad only ever cared about delivering Cav to the line. I doubt we'll ever see such a dominant sprinter and sprint team as that again.
It took Cav two years from becoming a pro to win a major race. Ewan won a stage of the Vuelta within 12 months of turning pro.
But yes, it is early days I guess.
