I feel both Adelaide and Central Coast relocations would be failed attempts. Adelaide just doesn't have the support base down there, and I don't think the NRL is willing to pump continuous money down there.
Central Coast already identifies with the Bears. As silly as it sounds, they already have support behind a 'Central Coast' team and with the Bears putting in a bid relocation to the Central Coast would be a failure.
What I would be working out with the NRL is a move to the Sunshine Coast. It has a large area to grow from, with a great amount of access to Queensland Juniors. The title 'Sharks' could remain because of the coastal region, as well as the colours.
Ideally in 2012, we would see the Central Coast Bears, WA Reds, and the Sunshine Coast Sharks.
