Queensland's spine has emerged as the defining feature of the 2026 State of Origin series, with rugby league experts suggesting the combination could eventually rank among the greatest in Origin history if it continues performing at its current level.

Writing ahead of the deciding third match, State of Origin legend Cameron Smith argued that Queensland's key playmakers possess the talent, composure and chemistry to build a legacy comparable to some of the Maroons' most celebrated teams. However, he also outlined what he believes is the only realistic strategy available to New South Wales if the Blues hope to win the series decider.

Queensland's attack has revolved around an exciting spine featuring Kalyn Ponga, Cameron Munster, Sam Walker and Harry Grant. Throughout the series, the quartet has consistently controlled possession, created scoring opportunities and responded calmly during high-pressure moments. Their combination has allowed Queensland to attack from anywhere on the field while maintaining strong defensive organisation.

Smith believes the greatest strength of the Maroons' spine is not individual brilliance but the way each player complements the others. Walker's game management, Munster's creativity, Grant's speed from dummy-half and Ponga's ability to join the attacking line have created multiple threats that are difficult for opponents to contain over 80 minutes.

According to Smith, the key for New South Wales is to prevent that combination from controlling the tempo of the match. Rather than focusing solely on stopping individual players, the Blues must dominate the ruck, win the middle third of the field and reduce the time Queensland's playmakers have to organise attacking sets. Fast line speed, aggressive defence and sustained pressure on Queensland's forwards are considered essential if NSW is to disrupt the Maroons' rhythm.

New South Wales will also need a strong performance from its own playmakers, particularly Nathan Cleary, who is expected to take greater control of the Blues' attack in the deciding match. Experts have suggested that if Cleary can consistently build pressure through his kicking game while limiting Queensland's field position, NSW will significantly improve its chances of reclaiming the shield.

The deciding match will be played at Suncorp Stadium, traditionally regarded as Queensland's strongest venue. The Maroons have built an outstanding record in Brisbane, and many analysts believe the home crowd could provide another advantage in what is expected to be a closely contested encounter.

Even so, Smith believes Origin history has repeatedly shown that momentum can change quickly. While Queensland enters the decider with confidence following a strong Game II performance, he argues that discipline, possession and winning the forward battle will ultimately determine whether the Maroons' celebrated spine is allowed to dictate the contest.

With the series locked at 1–1, the final match promises another classic Origin showdown. If Queensland's playmakers perform at their best, they could strengthen their reputation as one of the competition's great combinations. But if New South Wales successfully controls the middle of the field and limits their influence, the Blues may yet spoil the Maroons' ambitions and claim one of their most memorable series victories.
