I agree that Ihaia West probably is no where on the All Blacks radar, but I think you're exaggerating saying he may not be ready for Super Rugby.
In this ITM Cup
His goal kicking has been fairly poor at 61% (many have been conversions from the sideline to be fair), while his tackling has been at 79% (a higher rate than Tom Taylor's this ITM Cup). Furthermore his tackling was almost exactly the same in Super Rugby at 78%, while he was kicking at 72% (ironically higher than Tom Taylor's kicking percentages in Super Rugby last year). I think he's actually a pretty tidy game manager. His running is obviously brilliant, but I think he has a good mind when to pass or when to plug the corners. Still early days so I'd like to see him get at least two or so more seasons of Super Rugby to improve before looking seriously at test selection.
I hope someone pays Daniel Carter a ludicrous amount of money after this RWC...maybe Toulon. They can give him some of the children's blood or baby's tears or w/e they were giving Wilkinson to stop him from breaking down all the time.
