Is Robbie Deans the right coach for the wallabies for next years world cup?

The players are the ones losing the games at present. Deans can't go out and tackle and p for them. However when things were getting tight and Sharpe left the field, Moore should have come on. His experience would have been beneficial to the team. As well, the Wallabies have played poorly in the second half of most of their games this season. This is something that the coach should have been working on. As well some players seem to be untouchable as far as their performances go.
