New Gold Cost Titans assistant coach Jim Dymock is ready to embrace his role as the "Minister of Defence" as he gets to work on improving that aspect of the game.

The Titans conceded 651 points in 2019, the most in the NRL. It was a major factor in their wooden spoon finish.

The Titans have let in fewer than 500 points in a season just four times in the club's 13-year history and in three of those seasons – 2009, 2010 and 2016 – reached the finals.

Massive improvements are needed and Dymock, who spent a decade at the Bulldogs and several seasons at the Sharks in a coaching capacity, is keen to play his role.

"It is not rocket science. Defence wins matches," Dymock told NRL.com.

"I think we have the strike power to definitely ruffle a few feathers but when you are trying to express yourself in attack you are going to come up with a few dropped balls and that is when you have to be able to defend your line.

"Last season they weren't good at it so that it is a big challenge.

"I am not here to go over what happened last season but my job is to make sure that the players all know their job and put systems in place so we have a safety net in place if something does go wrong so they are all accountable."

Dymock represented NSW and Australia and was a creative ball-playing lock and five-eighth for Western Suburbs, Canterbury and Parramatta.

It is the defensive ethos of Canterbury's 1995 premiership-winning side - which conceded just 28 points in four finals matches - that Dymock intends to instil into the Titans.

"I remember one season our attack was woeful but our defence was still good and we still scraped in [to the finals]. When you are on and your defence is humming you enjoy defending because you get an opportunity to inflict pain on the opposition," Dymock said.

"Then, when everyone is on the same page and on song, it is just beautiful."

Dymock will be working closely with the Titans forwards on both attack and defence. He is enthused by the calibre of player that he has to work with.

He said the Titans had the players to do the job with elite forwards Jai Arrow, Kevin Proctor and Ryan James on board and quality young stars such as 2019 player of the year Moeaki Fotuaika in the squad.

He also has a strong rapport with new Titans head coach Justin Holbrook who was on the coaching staff at the Bulldogs when Dymock was there.

"Justin impresses me because he doesn't over-complicate things. He is going to strip it all back and simplify things for the players so everyone knows what their job is so that no-one is second-guessing themselves,” Dymock said.

"He is really big on the individual knowing their job but he also knows how to make training enjoyable."
