Starting supersub against Pumas in No 10 jumper this weekend would be ideal way to gauge sort of qualities required next year as World Cup looms
Starting Beauden Barrett at No10 for the All Blacks has been an exercise in frustration - whenever it seems likely, a reason for it not to happen has cropped up.
The selectors want to see him start at first-five before the World Cup. He's done plenty from the bench but, given the injury toll that struck their No10s in 2011, the All Blacks think it would be wise for Barrett to have experienced starting a test at first-five at least once before then.
His only other test starts being at fullback, against Italy in 2012 and Japan last year.
Barrett was set to start at first-five this year in Hamilton until Conrad Smith broke his thumb and the selectors decided they didn't want to make two changes to their midfield, sticking with Aaron Cruden.
