I don't know, I think it's a little demeaning to take him on road trips just so he can feel part of the team he's probably never going to play for again. It really is like he's a mascot now. I'd be embarrassed to have a role like that. By all means give him a role in the footy department though.
I don't think so.
He's still a very good footballer - he goes and gets 30 touches a game in the VFL and lays 6 or 7 tackles every week.
It's just his speed, vertical leap and kicking distance which is not AFL standard anymore.
He would not embarrass himself in the senior side by any means, so I don't see why having him as a travelling emergency is demeaning whatsoever.
