I think the club has come out and said that Carney would be the man, although I am sure this could change. From watching PL and Flegg in 2005, I would probably have Dobbo as the better kicker, and then of course he had a fantastic record in the ESL.
If Dobbo plays early I would give it to him but I suspect Carney will get the nod.
Carney actually has a 100% record in the NRL (6 from 6 - 4 v Newcastle, 2 v Parramatta).
However there is no doubt who ever it is, they are not going to show the sort of form that Clinton showed over the past year or two. He has been recruited to Union for his goalkicking as much as anything else.
