NRL.com analyst Matt Elliott takes us through three key points ahead of the State of Origin series decider.

The Breakdown: How to win Origin III

NRL.com analyst Matt Elliott takes a look at three key factors ahead of the 2015 Holden State of Origin decider at Suncorp Stadium.

Elliott, who has more than 270 games of NRL coaching experience, explains what the return of Cooper Cronk will mean to the Maroons and his partnership with Johnathan Thurston.

He then analyses Greg Inglis's move to fullback in place of the injured Billy Slater. Will Inglis be more potent at the back rather than at centre for the Maroons?

The Breakdown finishes with a look at the NSW engine room – Aaron Woods, James Tamou and young gun David Klemmer, to see how big an impact they will have on the Queensland forwards.
