I think we need to keep him for three reasons:
1. We need the depth he brings for 2012. If the first choice back line is K.Stanley, Nightingale, C.Stanley, Coops, BMoz, Soward and Hornby, we've only got Vidot as credible cover for injury in the three quarters and Fien for the halves. Without Moltzen, we're a couple of injuries and a rep weekend away from Bronx Goodwin, Reece Simmonds and Peter Cronin playing a scary amount of first grade. At the same time, we just don't have the good junior backs coming through. There's Evander Cummins and that's it.
2. If he stays at Wests Tigers, he targets a direct competitor for the 2012 season. Even if he sulked in reserve grade for the whole season (which I doubt he'd do) he makes it easier for us by weakening an opponent with equivalent ambitions.
3. As I've said in other posts, we're a bigger club than they are and we need to act in accordance with that relationship dynamic. They cannot get what they want at our expense. Clubs that win comps are big hitters politically as well as on the field and we have to flex our muscle over this. Doust needs to know that we are watching him and we expect him to act in the interests of the most powerful club in NSW.
Finally, let him whinge in the media. When the dust settles and he's made to commit to his contract with St George he will realise he has no choice but to play to the best of his ability. He will be in a competitive side that might not win in 2012, but has the foundation for at least one more premiership in the next 3 or 4 years.
Carney would be interesting on a one year incentive based contract but you wouldn't want to bank on him. He'd need to be worth 10-12 points though, because our back line defence with him, Soward and Stanle in key positions will leak an extra 6-8 points next year than we've been averaging for the past there years under Bennett.
