New Wests Tigers coach Mick Potter says he'll make subtle changes to the way the NRL club plays the game but he won't be putting the shackles on star playmaker Benji Marshall.

Potter was unveiled on Wednesday as Tim Sheens' replacement, signing a two-year deal with the Tigers.

The former Canterbury and St George fullback built a reputation for himself as a mentor during his seven years abroad, being named the 2012 Super League coach of the year.

Sheens' 10-year reign at the joint venture ended last month when he was relieved of his duties after the side failed to make the 2012 finals.

Sheens has been offered a development role with the Tigers and the club is awaiting a decision from the veteran on whether he will stay.

"I'm really looking forward to working with some senior players like Braith Anasta and Robbie Farah and Benji," Potter said.

"I think they play an open brand of football and probably just had a few too many points scored against them."

Potter, who clocked on for his first day at work on Wednesday and met prop Aaron Woods and centre Chris Lawrence briefly at Concord Oval, said it was too early to give his assessment on where the Tigers are at.

"Give me a week or two and I'll be better prepared for that," he said.

"I've got my own ideas and my own thoughts on some individuals and the way we play but I'd rather just get on with business at the moment and worry about the football side once pre-season starts."

Potter said it was crucial not to weigh a player like Marshall down with too much structure.

"You don't want to stifle a player like Benji and I think if you look at some things that he does ... he creates space for other people and creates space for himself and he's very good at it and I don't want to stifle that and that's his style," he said.

"But certainly I'll make some subtle changes, not to his game but to compliment some other people because it's a team game ... to get the best out of everyone, there might be some subtle changes."
