The risk isnt on field. Hes a proven goalscorer and very good player. The risk is the PR disaster that would happen if we went through the process of getting him and he walks out on the club before hes played a game, or very early in the season. I think its something that would be very likely to happen. I can see him, especially if he gets injured or something, "losing the passion" and retiring.
I actually don't think it would be a PR disaster (and I know that is asking a lot of the Adelaide media) but I think it would be more like the Cousins story. The media would be so keen to build it up as a good news/resurrection story and so keen to avoid coming across as racist that if it all turned to shit they wouldn't go too hard.
Assuming all his court case stuff is over that is.
If the court case is still hanging over him I would still rookie him (unless they have good advice that he is definitely going to get time).
