You miss the point Leon. Our main Coaching team has 2 Wingers/ex wingers and a Forward. In my opinion I feel it would be good to have somebody who has played in the halves or at Hooker.
Wayne Bennett had for example Craig Bellamy on his coaching staff whg had played Halfback and lock for Canberra as well as. Chris Anderson wasnt an out and out winger and played many games for Fax at 6. Michael Maguire has Kurt Wrigley as an assistant who has played halfback and Wayne Collins who played hooker as his assistants. A coaching team is more than just about one person, but a team effort with people who have experience in a number of positions to offer advice. Having one of the assistants who has played at a similar or higher level at 6,7 or 9 would be better in my opinion.
