Spot on, except for Barrett's kicking imo. He had the worst kicking stats for top tier nations in 2016 and hasn't improved since. He's hovering around 70% which is really poor for an international 10, even 2nd tier teams.
On the ABs going for a try vs a drop goal topic: it's clear that the ABs focus on high payoff areas of the game. In it's most simple form, scoring tries and stopping their opponents from scoring tries.
What makes rugby union a great game is all the aspects you need to be good at to be a 'total' team. And also being able to score in all the possible ways. The All Blacks aren't good at drop goals, and off the tee in general lately, so therefore they weren't good at scoring enough on this occasion. It hasn't cost them the last 9 years / 56 out of 57 matches at home, and it probably won't for the next 50+ games. They got caught out by a determined Bok team who outscored them and pressed them the right way, as only the Boks historical have.
If I was the All Blacks I too would have gone for the try because they were literally inches away from Ben Smith racing into the corner and the whole world cursing of another typical AB victory. DM's knock-on was a forced error. If they went for a drop goal and missed it would have been an unforced error.
Excluding Sexton's drop goal (absolute balls of steel to take that one) the other drop goals mentioned that won important matches were not at the death, therefore not an all or nothing option. They were typically near the end and gave the team the points needed so that they put the ball in the other team's court to come up with extra points.
That said, as a Bok supporter it's awesome to see the cat being let out amongst the pigeons in some NZers psyche about this loss
I don't think the ABs would be over analysing this one though
