If Mateo is the one providing cover for the halves, a couple of questions.
Firstly, is he any good in the halves, and apart from his offloading game, what attributes will he bring. Kicking game etc. Having played over 200 NRL games, I would think he is a good player.
Also, at 32, and 17st, is he quicker then Finn. A lot of bigger players tend to be slow on cumbersome.
Only asking, as I don't watch a load of NRL to be honest.
My initial thought would be to play 13, assisting the halves
