"How do you define the greatest player of all time? I can't do that, but I can tell you he's in that category.
"The influence he's had on the game and the way it's played, the players that have wanted to be like him are many.
"I think that's the greatest legacy for players, is that young boys growing up and see him play want to be like Benji, Andrew Johns and Allan Langer – all those wonderful players I've seen in the last 20-30 years.
"He'll be up there in those conversations. He's won premierships, World Cups and done everything the game can offer."
Marshall's former clubs, Wests Tigers, St George Illawarra and Brisbane Broncos, also paid tribute to the 36-year-old's achievements throughout his career.
He was awarded life membership of the Wests Tigers in 2013 before his brief stint in rugby union followed with stints at the Dragons and Broncos.
His return to the Wests Tigers in 2018 was a celebrated homecoming but the club's decision not to re-sign him last year saw him finish his career in the red and green of South Sydney.
"Wests Tigers would like to extend its congratulations to Benji on a magnificent career and his exceptional contributions to the club throughout his 14 seasons with Wests Tigers," his former club said.
"The club wishes Benji, his wife Zoe and children Fox and Ever, all the best for the future."
The NZRL paid tribute to Marshall with a tweet congratulating their international player #717.
