Boyd Cordner has endorsed Cameron Murray as a serious option to succeed him as NSW Origin skipper once he stands down from the Blues' top post.

And Murray, the 21-year-old seen by many at Redfern as the future South Sydney captain, credited Cordner for helping him be better prepared for this year's NRL finals series.

The game's best leader and the youngster tipped to one day lead NSW and even Australia will lock horns in the middle of the SCG as the Sydney Roosters and Souths renew their rivalry in a Friday night SCG qualifying-final blockbuster.

At just 21, Murray has won over plenty of experts and fellow players with his natural leadership qualities, including the Roosters, Blues and Kangaroos captain.
