Credible, all I can say is it people involved with 3pas
The Dogs do want JAC, the Storm do want Lewis, the dogs are reluctant to let Lewis go, their may be other swap options, this is a fluid situation, but they are definitely in discussions. This is a still a rumour until it is finalized.
The other ones I reported are no longer rumours they are fact and will happen, Mitchell, Johnston, and Xerri. The only fluid one in those is Arrow joining Souths this season, but it is expected to happen before the end of jan. I have a Rabbitohs mate he knows plenty of Souths supporters jumping on their odds, as they believe by next week they will be halved, one guy placed $20K at $14 for them to win the premiorship.
