Not sure I believe McRae giving the impression they won't be signing McDonnell.
It's not like you hang around for a player in a key position who would take around 80-100k on the salary cap to "let you know" that he might be interested in a contract if, come October, his NRL options have not come off.
If that was exactly the case, McRae could rule out signing him as we would need to be allocating the cash elsewhere. That he give such a nuanced reply suggests he could well be coming to us even if the ink isn't yet on a contract.
