I can see why Pearce is up there, he was still playing well at NRL level this year. I think he's a good addition for Catalans as is Dylan Napa.
On Cust, he showed some good touches in limited game time for Manly last year from what I saw. I think Brodie Croft who's gone to Salford, is another half who could go well.
Brandon Smith has signed with the Roosters for 2023 onwards. He's a hooker or 13 and one of the best in the sport in either position.
