I dont see why it should take too long to have him footy ready. Barba doesnt have to be completely exorcised to play footy. He just has to get to a stage where he can play and has ongoing maintenance and support for his issues. I know the issues may not go away overnight, but all humans face issues. You have to firstly confront the issues, break down/identify the causes, and then make a plan to overcome them (and stick to it). Training and playing may help him at some point. One it would give him a lot less free time and two the discipline of training, and support of team mates cant hurt him.
I couldnt take months off work because i had some issues. I have responsibilities.
