If Luai comes, he will play 7.
I think Sullivan will be the most likely to drop off. Sullivan was only signed to cover the halfback role in the event that we don't land a big fish over the span of his contract. We land a Luai type? He'll be down the pecking order quickly. Fortunately, he still has utility value at 14. The flip side to that is that he explodes and he very quickly realise we don't need to land a big halves fish.
Latu will be the 5/8th, if not next year at some point, then definitely in 2025. He's here for the long haul.
Galvin will be next on the card and, as many have said, I'd say he'd be given a soft entry into either centre or backrow. His versatility and frame actually make him more likely to fill a spot in the 17 in the future as he could foreseeably gain valuable bench minutes for a year or so, then move to anywhere from centre, second row or lock as needed. He then also provides good 5/8th cover in the meantime. This is 2025/26 and beyond I think.
Large is probably the final consideration there, but he is 16. He may play first grade at 19 if his current trajectory is anything to go by. So still 3 years away from even a taste in my opinion, we're talking 2026/27. Once again, as with Galvin, his versatility may allow him to enter as a centre or even winger at first.
Long story short, there's a few scenarios that could play out, but personally, I think if a Luai-type is nabbed, it'll be Bud that slides down the pecking order unless he develops out of his skin, which, given his junior pedigree as well, is entirely possible.
