I'd be enquiring about Isaah Yeo, David Mead, Connor Watson, Joseph Manu, Curtis Scott, Tevita Pangai Jnr (Balmain Jnr his two brothers played for Balmain) and Roberts.
Isaah Yeo is locked up at the Panthers. long term but otherwise yes.
David Mead - yep, definitely. Bennett won't release him this year but for next year he'd be a good wing option if nothing else.
Connor Watson - would we worth asking about even though he's signed up to the end of 2018\. They seem pretty happy with the Keary/Pearce combo and they have Matterson for depth at 5/8\. They might release him if he gets an opportunity to play 5/8.
Joseph Manu - no chance Roosters will release him. They'll move on SKD and Tupou before they get rid of a young talent like that.
Curtis Scott - worth looking at, although I think the Sharks are after him as a replacement for Bird.
Tevita Pangai - no chance of getting him off the Broncos. They paid good money to get him off Canberra.
Roberts - which one?
