I remember a prop saying that playing on the opposite side of the scrum is like trying to write with your wrong hand. You develop different muscles depending on your chosen side. I’m told this was not such a problem in the old days as props just propped wherever. I would guess that it’s easier to go from tight to loose . Bomb seemed quite good at it for us.
Genge conned Carly all afternoon which ultimately won them the draw as any scrum in the last ten was useless to us even on our own put in.
