Luai will go on strike if we play him as a 13.
Out of the three Latu Fainu is the most likely to be able to play as a 13 anytime soon, but I can’t imagine him being happy about taking on that position full time.
I think the only scenario that might work is playing Fainu as a 14 and letting he and Galvin share the 6 and 13 role for parts of each game. Would be unfair on them and the team to make any 18/19 year old 5/8 to start or play full games at 13.
Listen, it's obviously not ideal, but here's a second question.
Everyone is saying what not to do, but the same people will be saying how we should have tried harder to keep all 3 if they are playing out of their skins and one leaves because we keep carrying one on the bench.
In that situation, what is the answer?
The Luai at 13 suggestion is based on 2027 or onwards. Not next year or the year after and depending on how Latu and Galvin develop.
I'm not even advocating for Luai at 13. Simply saying if you are going to try and move one of the halves to another position over time, then Luai fits lock better than Galvin and Fainu. It COULD be a solution depending on the landscape at the time.
Secondly, watching Latu on the weekend, it's clear he is 1 or 2 years off. Now we are looking at an ageing Luai, Galvin with 2-3 years under his belt and Latu with 50 games experience around 2027 or 2028 season. At that stage, Luai might be happy to shift depending on form.
All this is a wait and see, but I don't think you can keep carrying a spare half on the bench because you don't want to lose them. You have to give them a path to full-time first grade and a position they can specialise in for the long term.
