One tactical change the All Blacks may make is to bring Tavatavanawai into the matchday 23, purely because he can cover the wing to a better level than the other midfielders.
I'd argue that DMac coming on and Jordan sliding to the wing changed the way we would have played to a significant degree. If Jordan is your fullback, then ideally he shouldn't really be moving to the wing unless there is an injury IMO. I think it is preferable that unless Jordan gets injured, that when DMac comes on, he replaces Barrett.
A spine of Roigard, Barrett & DMac is too far in the direction of risk-taking and needs to be balanced with a safer pair of hands (Jordan).
