Crichton set to step up as Blues starter

"I think Roosters put me in good stead for big games and in the NRL you have to prepare for your best every week so I'll do my normal preparation," Crichton said.

"It's different [starting]. When you're coming off the bench you have to prepare for anything, you don't want to get too amped up too early, you want to save your energy. You don't want to waste all your energy sitting on the bench.

"It's a really clear role for me this week and I'm very excited to go after it.

"By playing a bit of centre, playing a bit of lock, playing on the edge, it gave me a greater understanding of the game, I got to learn about other people's positions and where they need to be [and a better] understanding on what role I need to have inside the team and the kind of game I want to build myself to be able to play."

Crichton took a pragmatic approach around his own demotion last year.

"It was tough but at the same time I knew I wasn't playing my best footy so you just have to be honest with yourself," he said.

"Coming back from a shoulder reco, I wasn't physically where I am right now so a lot of work's been done between then and now.

"I'm really excited to be back in this arena and plying my trade."

The 24-year-old won't be worrying about trying to replace Cordner when he runs out on Wednesday night.

"I build my game around strong defence and strong attack. Being tough to tackle and making tough tackles on them, that's the long and the short of it," he said.

"My focus is very clear, I've got all the details into it by now, captain's run tomorrow, let go of all the details, all the work's done, let instinct take over and then just play the game.

"I'm my own player. It's obviously unfortunate circumstances for Boydo who's a good mate of mine as well, my thoughts are with him and what he's going through at the minute.

"He's made the right call for himself and I'm sure he's done the right thing.

"I spoke to him before he took off, said goodbye and had a bit of a chat then sent him a couple of texts here and there. He's doing really well. He's back home with his partner.

"He'll lay low in Sydney for a bit, get away from footy. It's been an intense year for all of us I think with the bubble and what not, we haven't been able to escape it all year.

"It might be a bit of a relief for him to get out of footy for a bit … you're always thinking, always wanting to get better [so he can] put that to the side for a week or a couple of days and just refresh."

Crichton had no doubt Cordner would bounce back, regardless of how long he needed to rest.

"I've got no doubt that Boyd can bounce back from this. He's a resilient player, he's a smart player," Crichton said.

"He's got a really good head on his shoulders and he's a smart guy so he'll make the right decision for himself. I'll back him to come back from it soon.

"He's one of the toughest players in our game without a doubt."
