I agree, we need a halfback.
Herbert doesn't have the tools to be a big game halfback now, I doubt he ever will and I'm not preared to give him 3 seasons to develop just in case.
I'd still go all out for Mick Monaghan, the guy has experience, great passing game, great kicking game (all round kicking game, not just chips) and can run the ball well instead of getting to the lin eand doing a jig.
He may never play rep footy, but he won't be far off.
Don't care what anyone else thinks, if we put him in our side next year, we're going to take it to all the top teams.
