It takes time to develop a team and many things can impact on the success or otherwise of that team that the coach can not control like roster and injuries.
Just look at Parra and Raiders. Everyone was baying for Stuart's head but he wasn't sacked and now look where they are. Parra wasn't flash for a few seasons either.
Bennett wasn't able to do much with Newcastle and look where Souths are. And so on it goes. Many factors involved in winning, not just the coaching. That's why a coach should be given every opportunity to prove himself. If a coach is truly no good it will be leaked sooner or later by the players themselves anyway.
