For all of Ireland's positives during their destruction of the USA on Saturday night, Joey Carbery endured a nightmarish outing at fly-half.
The young Leinster star was charged down twice inside his own 22, errors which resulted in two U.S. tries. His place kicking, too, was off-kilter, and he eventually hobbled off on the 50-minute mark having suffered his poorest display in green.
He remains a sensational talent, of course, and at 21 has ample time to establish himself as an international. But speaking on Eir Sport after Ireland's crushing victory, former Irish head coach Eddie O'Sullivan explained that Carbery would find it difficult to break into Joe Schmidt's reckoning ahead of Paddy Jackson after such a paltry display.
O'Sullivan pointed out how poorly Carbery was positioned for both charge-downs, and broke down his struggles accordingly.
The 21-year-old is a doubt for Ireland's tour of Japan having suffered an ankle injury, but when he does return - be it at 10 or 15 - he'll surely enjoy the first finer performance of many in international colours.
