For the second straight season Bombers will go into the decider in a strong position having yet dropped a match, with the competition benchmark winning all 12 of the home and away games before securing a spot in this weekend's big match with a 55-point semi final victory.

The record of the past two years will see Bombers go into the game as red hot favourites, but joint-coach Jake Williamson said he and Rob McAdie will be mindful of keeping their charges focused on the task at hand.

"The boys have travelled through the season fairly well, their confidence is sky high and I know that can be sometimes be a burden," he said.

"The message will be to just play this game the same as any other home and away match, there is no reason to divert to anything else.

"What we have done right through the season has worked."

Bombers' ruckman Aaron Byron will be very important to the team's fortunes in the grand final, with the talented tall impressing throughout 2014.

Byron has the ability to cover the ground well and give his onballers first use. At Byron's feet are the likes of Ryan Weppner and Archie Conboy, who both ooze class.

Weppner, who has 'all the tricks of the trade' according to Williamson, is very good at feeding the outside runners, while Conboy does the majority of the Bombers' grunt work to win the ball in and under.

In the forward line Bombers best avenue to goal is through leading goal kicker Mason McLaren who has come along in leaps and bounds this season, while Shaun Vermeend is a dangerous 'goal sneak' who works hard to apply pressure on his opponents.

Rounding out a solid Bombers' outfit is the backline, which is led by reliable defenders Brenton Lewis and Josh Wilson.

The pair play the shut down role well and are good at sharing the ball around with their team mates to propel into the attacking end.

Williamson said Bombers' ability to win the ball will be vital if it is to claim the shield against Mounties.

"We get in there and win the ball, but also we don't turn it over that easily, we can keep possession," he said.

"Once our opponent does get the ball, the boys apply pressure really well through their tackling.

"They just need to be a bit more accountable, that is what caught us out in the first half of the (semi final) against Warriors a few weeks ago.

"We weren't that accountable when they had the ball and Warriors got the jump on us and we had to work hard to get the lead back.

"We can't afford to do that against Mounties accountability is a big one this week."

While Mounties will go into Sunday as the underdog, coach Mick Driscoll has full faith in his players and said the team is starting to peak at the right time of the season.

"My boys over the last month have shown plenty of faith in themselves, everything I have been trying to teach them they are now putting it together," he said.

"That is starting to show out on the ground. We are willing to work as a team.

"We don't work as individuals, I rely on all 21 of them, from the top age to the bottom.

"I keep saying to the young kids, it doesn't matter if you only get one kick or one possession, even if it is just a smother, that one thing might be enough to helps us win the game."

After only winning four matches during the home and away season, Mounties has saved its best for the finals with a 42-point win over Rovers in week one, which was backed up last Sunday with an upset in the preliminary final over the higher ranked Warriors by 24 points.

Captain Lachie Holm leads the way in defence alongside Alex Asuncion, while in the midfield there is no shortage of talent.

Matthew Spalding and Flynn Jamieson are a good running duo, while on the wing Jack Driscoll and Tom Cousins give the side plenty of drive.

Ella Wood is another player who has had a solid impact in her first year playing football, along with Kaiden Walton, who is a capable goal kicker.

Driscoll said Mounties has continued to show improvement throughout the year and believes his team can pull off another upset, they just have to believe in themselves.

"The first time we played Bombers we lost by about 14 goals right through to the last time we played them where we only lost by a couple of goals," he said.

"We are slowly pegging them back, so who knows?

"It is a grand final, anything can happen you've got to be in it to win it.

"At the end of the day if they don't win it is still a great achievement to come from being on the bottom at the start of the season to where we have finished now."
