However that has wavered in recent times, to the point where he was unwanted at St George Illawarra and facing retirement until the Broncos offered him a lifeline.
But with Ben Hunt and Anthony Milford ensconced in the Brisbane halves, the 31 -year-old said he was likely to be used in the centres in 2017.
And while he's played just one match there since 2004 for the Wests Tigers, he believes it could help revitalise game.
"I didn't come here to play in the halves," Marshall said.
"When you play in the halves you've got to do a lot of organising and sometimes you can forget about what you do yourself," Marshall said.
"I think over the years I've done a lot of ball-playing for so long I've forgotten about my running game and that's something that I stressed to Wayne that I wanted to find."
Marshall is under no illusions about the certainty of his starting spot at the club, having already been warned by Bennett there's a chance he could play in reserve grade.
It's why he's now bracing for one of the most important pre-seasons of his life.
"I've got a lot to prove," he said.
