Ross Lyon is hardly going to lead into his negotiations with his club by saying...."yeah i might stay, but I might go". Hardly as strong as saying "I'm commited to this club, I have a vision, all I need is you guys to back me". The latter keeps the players support and puts the acid back on the board.
I think StKilda may re-sign him simply because they are concerned about the alternatives available, but he's not staying or gone until I hear the words from his mouth.
Lyon is doing the best possible thing now and keeping his mouth shut until he's done negotiating.
