Captain Ryan James has called on his team-mates to improve ahead of the match against the Sharks at Cbus Super Stadium tomorrow.

The Bilambil junior isn't happy about the lack of consistency and believes it all starts with the defence. James in not shying away from it himself, calling out his own defence.

"Everyone has to improve their defence," James said. "I had the most missed tackles in the whole competition earlier in the year and we just all need to work on it."

With Bryce Cartwright replacing Kane Elgey at five-eighth the discussion all week has been based around what the Penrith junior can produce but James knows his forward pack need to play their part.

"It's always good when they're going well (the halves) but we need to go forward and lay the platform. We have to produce quick play-the-balls and they can play off the back of that."

Another new addition to the side is Runaway Bay junior, Brendan Elliot, who will become Titan #138, lining up at left centre, outside of Cartwright. With the new combination it is thought that they'll have a fair amount of Sharks traffic coming towards them.

"He's played for the Roosters and Knights. Good for him to come home, he's had a fair amount of first grade experience and should be able to handle it out there without any trouble.

"We just need to work hard in the middle and make it more comfortable for them out wider."

The 26-year-old will tomorrow partner milestone man Jarrod Wallace in the front row and after recent speculation regarding his future, hopes the pair can stay together at the club for a while yet.

"I played SG ball with him and he went away and came back. He's a great front rower and has got a good footy brain.

"We're the same age and hopefully we can build together and with the back rowers and Jai Arrow at lock it'd be great to stay together."
