I'm pretty sure McKendry has played just a handful of (trial) minutes in 14 months - caveat emptor.
Kikau has been playing on the edge a fair bit at the end of the season (ISP), so perhaps he's looking to move, or the Panthers are looking to move him? Or maybe they just think he's better there... In any case, in the middle he's got good go-forward but big defensive question marks.
Browne is a bit-part guy, I'd much prefer Latimore (who I'd also be more confident of getting more minutes out of when needed). But still, if he's at the right price he's not someone I'd complain about.
Any Latu deal seemed dead.
Leota? Would have to look deeper but seems promising, if raw.
Is the Panther necessarily a prop? Because Whare could well be out of there, given that he's seemingly lost his spot (though he did sign a long new contract this year). Otherwise... I'd take Darren Nicholls as competition for the 6 against Ata/Lino in a second, or Luai could be an option for the same (he's a Kiwi too I believe).
