Yes, Tupou's spot is taken up by Allgood.
This is one thing that concerns me about overseas players, and the quantity over quality debate we seem to have in Super League.
We are full now on the quota spot, but I can think of a player in our squad, who probably wont't make our first choice 17, and that the British players we have in the squad, are probably ahead of him.
I also just hope Fifita makes a good go of it, as although I do like him, I'm just not sure that we were top of his wish list.
At the end of the 2016 season, there were more NRL hookers off contract than there were SL hookers.
Personally, I would go look at a British hooker, probably out of the championship, offer him a one year deal to see if he is right for us and vice versa, and if it is going well then look at extending the deal.
