Jamie Peacock believes the Bulls can still achieve Grand Final glory if they can just stop playing "dumb football".

The Bulls forward made the bold declaration after his side suffered their second straight defeat at Odsal.

An error-strewn and indisciplined Bulls performance allowed Wigan to grab victory without ever playing brilliantly and despite both sides running in four tries apiece.

"We have to stop playing dumb football," said Peacock, voted man of the match by the home fans yet again in the Saturday night Sky game.

"We haven't been playing at our best the last few weeks. We are just doing stupid things and not listening to what Nobby (Brian Noble) tells us. I still think we can turn things round, we are in a good position and have the team to win games. I think we can still win the Grand Final but we need our injured players back and we need to play the way we know we can."

The Bulls have been off the boil for a month now, ever since their 13-game winning run ended at home to London.

But Peacock believes things could be a lot worse.

"After a Challenge Cup final a lot of teams go through a slump," said the Great Britain international, expected to be picked for next week's Origin game at Odsal.

"Traditionally teams struggle but we haven't done that. We kept winning after our trip to Cardiff and had that great performance when we beat Leeds here to go top of Super League.

"But we just need to get back on our game, which I am sure we will do soon."

Coach Noble wasn't over-impressed with his side's performance, particularly in the first half.

"We didn't handle the first half very well and in some respects gave ourselves too much of a hill to climb.

"I'm not going to fault the effort but it wasn't to be. Early in the game we couldn't find the last play for ourselves and it was the lesson we deserved."

Meanwhile, opposite number Stuart Raper was delighted.

"It was a very impressive performance," he said. "I've got to give big raps to all the forwards.

"It is a satisfying win. To beat Bradford after seven games of losing to them is good, and part of our building process in the last two months."
