McCullough key to grand final glory

NRL: Dual premiership-winning rake and Broncos legend Kerrod Walters says hooker Andrew McCullough is as important as any other player in Brisbane's quest to claim a seventh NRL title against the Cowboys on Sunday.

McCullough has been instrumental in Brisbane's charge to the 2015 decider and a Broncos win on Sunday could edge him past the Roosters' Jake Friend as the man most likely to one day take over from current Maroons hooker Cameron Smith.

Walters, a current Sunshine Coast Falcons board member, described McCullough as a consistent performer who invariably made the right decision.

"His performances are always at a high level and he makes very few errors and I know that is something that pleases Wayne (Bennett) a lot," he said.

"He handles the footy more than anyone and comes up with the right options all the time and hopefully that will be the case on Sunday."

The Broncos have bucked other teams' conservative styles of the modern era by playing an expansive brand of football, relying more on chancing their arm than rigid game plans.

Playing such football could be attributed to their success this season, with teams struggling to defend such openness as opposed to some other teams' unadventurous attacking structures.

The Cowboys play much the same way, setting the stage for a mouth-watering high-scoring grand final that could go down to the wire.

"Obviously in their last meeting (September 12) there was only four points in it (Broncos won 16-12) and it was a cracker of a game," Walters said.

"We won at home and they won at home (during the season), so if you can go on past games this year, there is nothing between the two teams.

"It will come down to some brilliance by someone and hopefully not a bad refereeing call.

"I am confident Brisbane can get the job done."

Brisbane have won all six grand finals they have played in (1992-93, 1997, 1998, 2000, 2006), all under Bennett, who also took the Dragons to a premiership in 2010.

History says when Bennett gets a team to a grand final, they win. "That is why the pressure is on these current boys because of the success of the teams of the past," Walters said.

"They have done everything right so far, so it is just a matter of them carrying out the game plan and doing whatever it takes to win.

"Queensland has been waiting for an all-Queensland grand final since 1995 and they have finally got it."
