Whoever misses out can feel a bit unlucky but it’s a good position to be in compared to last year when an injury or two meant having lolohea, lesser WZ, Naiqama (at fullback)or an underdone Fonua lining up.
When the grind of the season kicks in it’s not uncommon to have one if not two backs injured at a time so I think Thompson, Nofo and Momo will all see plenty of game time even if they aren’t in the side come round 1.
