there is a general consensus amongst the Wests boys that they want to "do a Penrith," implying that they want to stay together and build a premiership winning side. couple that with the fact that the large majority of the guns (including the players you mentioned) have been locked up long term, and that will certainly help us into the future.
they can't do it on their own though. we need experienced, toughened first graders who can show them the way and assist them in showing them how to win and play consistent week to week footy. this is why an experienced half is so important for these next couple of years.
also, Galvin will be a backrower. club has identified him as such and that will be where he ends up. there is a chance he may do a Wade Graham or a Matterson, who starts off at 6 and then shifts to an edge, but that is the plan. that may slow his path to first grade further as he's 80 kilos wringing wet.
Onitoni could easily play halfback or 5/8, he's genuinely that good, but I think Alex Conti is the most natural halfback in the pathways and moving Onitoni outside him will be of a benefit to both of them, pending of course they remain on their current trajectories. Alex definitely has some growing to do, hopeful he's doing a preseason later this year.
