Although you are correct in saying Hiroti has already had a long career playing Reserve Grade and signing him could potentially be another Brent Naden type situation, he is still only 26y.o he has had a few injuries that have held him back, but he now appears tj be on top of and it is quite hard to wirk out why he has not phayed more regular NRL as he has always played extremely well in his NRL opportunities such as this season with the Sharks and quite a few years back when he was at the Rabbitohs.
I think he would be a good signing to add depth, competition for NRL positions and not simply allow our young up and comers such as Makasini and Laulilli an easy pathway to regular NRL unless they well and truly earn it.
