why would we talk about tracey and hiroti when we have iro and taukamo?
Taukamo is injured, and has never played a game at fullback against men.
Iro is outside the top 30, and while they certainly
could upgrade him, there isn't a pressing need for it unless there actually is a long-term injury or two. He has also played very little fullback against men, and had dicks for fingers in his one NRL game.
If Kennedy is injured for a week or two, it will be Tracey who comes in imo. If he's out for a month you look at other options. I don't think Hiroti is the answer for the Sharks, but he might get the nod for the Jets. He's a good player at that level.
Probably something overlooked here is that Dykes was also injury cover at 6. If we are talking upgrades in to the top 30 I'd say Puru is every bit as much a chance as Iro.
