Personally think Souths are throwing up another smokescreen here.
Bennett has categorically denied two things:
1) They will not release James Roberts (the man he also claimed they were not going to sign)
2) They will not sign JAC, due to cap space
For me - it's just bitter old man talk. In order for them to accommodate JAC, JR will need to be released to free up cap space. But in order to do that, he will have to rid himself of a player he fought so hard to bring over.
I will cream myself if we get JAC, but I can see JR going to Melbourne (the Bellamy effect) and JAC going to Souths.
