I'd argue NZ have persevered with the same coaching system and coach generation system for too long. It's an idea that worked for them from Henry to Hansen. But in a game with developing new ideas, it my be restrictive. I'd argue not hiring Scott Robertson was a mistake by NZ, he'd have been a risk at international level, but he shows creativity and clever tactical decisions. I reckon that's what NZ are missing, new ideas.
Also Rossm, I'll miss your Bart Simpson profile picture.
