France name the same XV, only changing two subs to face Springboks

Both of those players just offer more of the soft distribution skills good centres learn from playing their careers there. Unfortunately that's what's lacking with the current combo.

Re lineout options, the ABs have the most innovative lineout in the world, with FOUR lineout options (Barrett, Vaai, Sititi, Savea), compared to Irelands maybe 2 (Beirne and Ryan). ABs will absolutely cause issues at the lineout, and definitely at scrum time. Those Irish props eat to much salad compared to our boys 💪

A game manager isn't exactly necessary, as the ABs should all know what they are doing, and the 9 should be directing the forwards. However, considering the youth of our best 9s currently, a more vocal, directive, and logical player like Harry Plummer would make more sense than someone like DMac, who is in his own right a good 10, but tends to sit in wider channels where he can threaten the line more directly, so has less influence on the postioning of the narrower forwards.
