I would be very surprised if he left Souths for anyone. I get the feeling that with Greg Inglis looking increasingly likely to leave in the next couple of years, AJ is someone who we seriously need to look a retaining. Also, if you guy or any other club wants to lure Johnston, I think your going to need to offer him a guaranteed fullback spot as well as any cash your prepared to throw at him. He has stated in numerous interviews his desire to play fullback and his team mates have also commented on his enormous ability in that position.
