West Coast wouldn't go anywhere near him even if they had picks. If he ends up back with his family about the only jumper he'll be pulling on is an Acacia Prison one.
If Richmond really want to keep him then they'll try to ensure he stays in Melbourne and gets on the straight and narrow. If they've let him go home then I'm betting they've given up on him.
My understanding is Syd got out of Adelaide as quickly as humanly possible and is back in WA.
