Yeah the batting is pretty awful but when you say 'only' its not really reflective. Keep in mind thats an average of 36 over 240 ODIs. If any of those guys in the top order for NZ manage that over 200 games kudos to that..
Fair enough but what is disappointing is that he averages 55 in test matches which is a big difference between formats.
As for averaging over 36 with our current guys when they end their careers I think Taylor, Guptill and Ryder will do it easily. Elliott probably not.
