Not to speak for Rhino as we all know he is more than capable of doing that for him self......
But I am not sure he is saying that at all, but that we as spectators or fans don't have any real understanding of the inner value or worth of Williams or any other individual assistant within the coaching staff and as such we must rely on those that do have that knowledge. And he was given another year to prove that worth.
We had a complete and utter clean out at the end of last year, and I would have thought (although I don't know) that if Bailey was of the opinion that Williams was useless or not going to contribute anything going forward, he would not have been included in the new coaching panel and would no longer be working for the Demons. And hopefully with a vastly better midfield to chose from he will be able to demonstrate why he is still there to those on the outer.
Just my opinion !!!
