As others have mentioned on here it's not solely Madge's fault that Souths are where they are, blame has to be put on the senior players as well as the hierarchy within the club.
There is a very long list of both half-backs and hookers that have left the club. Yes you are always gonna get players leave for various reasons but for me a lot have left due to the short-sightedness of the club thinking certain players were surplus to requirement and this comes from those in-charge not just the coach.
Madge can only coach/manage those players that are given to him, having said that to keep putting Talakai on the pitch for 80 minutes week after week is a massive mistake and to play to a very similar game-plan week in week out is not acceptable.
Souths are in dire need of some hard running, skilful back-rowers in the mould of dare I say it Glen Stewart (but without the problems he brought to the club) or a Luke Lewis to give the opposing defences something to worry about because it's so predictable on the second and third play of the balls to where the ball is going.
For me the following players need to be shipped out..... GI (knackered), either one of the Burgess Twins (living off a reputation) and Kyle Turner (decent player but never reached the heights as expected)
This would give the remainder of the team the kick up the backside that is needed and to show that no one is safe from being shown the door and also free up a lot of cash!
If we sign a couple of (very decent player makers and a back-up hooker for Cook) over the next few months, to then start training with the squad in November, I would then give Madge until R5 or R6 and if we are still playing the predictable 4-5 hit-ups and then kick, then I think he (Madge) should then be replaced.
