Not sure if its been mentioned here, but I think Aidan Sezer would be exactly what we're looking for. Getting him an early release from the Raiders would be difficult though, especially with our recent history with Ricky Stuart.
Sezer has a great long/short left foot kicking game, is a quality goal kicker, has good ball playing ability and pass selection, knows how to control the tempo of the game, and rarely looks fazed under pressure. I think he could solve pretty much all our woes at once.
The other thing which I feel makes him the perfect fit for our team is that Sezer isn't a dominant halfback like Thurston or Cronk, who are constantly on the ball pretty much single-handedly running the show, but instead Sezer goes about his business unnoticed, yet directs the team around the park so that the strike players in the team can shine. This would allow Milford in particular to take control of the team's attack and to be able to play freely without having the burden of organising etc.
