Writing for The Daily Mirror, Peacock says: “We had one very good performance against New Zealand where the team was unlucky not to win, and then played well in patches against Scotland and Australia.
“It’s not an effort or commitment problem – it’s elementary mistakes that have cost the side. You can’t come up with errors like missing penalties to touch at this level – cut those out and the team absolutely has the capacity to be successful.
“The good thing is that the players are fully aware of that, and it’s down to them now to cut those mistakes out.
“I’m also absolutely convinced that Wayne Bennett is the man to help us lift a World Cup. He’s set a good foundation this year in terms of what he wants from the players – how he expects them to play and train.
“I think it was a bit unrealistic to expect him to come in and oversee immediate success, particularly at international level.
“Sometimes in the sporting world you get to meet people who are deemed to be legends, and you can be disappointed. But Wayne has been everything that everybody says about him and more – and that’s unusual. I’m sure he’s exactly the right man to give us the best shot in the World Cup.
“Half-back is clearly still an issue for the side, although I think it’s good that all four players have had that exposure of playing and working together.
“It gets the team together again and gives us another chance to look at those half-backs – it’s a great step forward.”
