Why was Dan Carter so good?
It wasn't because he blindly followed orders.
It wasn't because he was a maverick.
It's because he largely did the right thing at the right time - game management which included a lot of kicking and running preordained plays, but also taking chances when he saw them. Presumably his coaches trusted him to do that. Generally executing well will have helped build that trust.
He was also surrounded by players who had the footballing brains to be able to adapt to the off the cuff. That didn't happen by accident and the Kiwis are probably still the best around at doing that.
Game plans sound great, but rugby's a multi phase game. How can you realistically have a sensible plan after the first few phases when players are all over the place (other than dully driving at the opponents line for about 37 phases). Framework's fine but prescription isn't.
On Cips sometimes it's hard to separate the views of the person from the player. On the field for the vast majority of most games he'd do the right thing. But coaches would know that he wasn't a total % player and that he would sometimes try things that others wouldn't even see. Sometimes they'd work, sometimes not but with players like that you had to work on the basis that the good would outweigh the bad more often than not. Maybe that's not for today's risk adverse analysts. But he won't die wondering. Faz might, Ford might also regret becoming a much more conservative version of his original self.
