I'd have a look at getting Flanno Jnr from the Dogs and giving him a run at 9. Would be cheap, so pretty low risk and worst case is halves cover for Nathan during Origin. The talk has been Manly for the rest of the year at around 60k, at that price it's worth a go.
He is a solid defender and effort isn't a problem. Just lacks what it takes to run a team. At 9 with us just keep it simple, make your tackles, provide good service and be another kicking option and have a few runs off quick play the balls. With the pressure off him to run the team and a change of environment could do him the world of good. He has some talent, it's just been lost trying to make him something he isn't.
And yes, I see the irony in my last sentence, but I stand by it.
