A triumphant Test series victory over the All Blacks in New Zealand provided Ireland with a significant morale boost ahead of their autumn fixtures.
That success allowed them to secure wins against South Africa, Fiji and Australia, which placed them at the top of the world rankings for 2022.
However, the team's standing among rugby's elite has become uncertain following the All Blacks' revenge win in Paris during the Rugby World Cup knockout stages.
Argentina, Fiji and South Africa are scheduled to visit Dublin over the coming weeks, presenting a chance to revitalise their momentum against Australia.
Ireland have suffered defeats by double-digit margins in their last six encounters with New Zealand, France and South Africa.
In those matches, they scored 101 points while conceding 191, with the most recent losses being particularly severe.
A 36-14 away defeat to France earlier this year in the Six Nations and a 40-21 loss at Eden Park against New Zealand were among the heaviest reverses.
The team's ability to perform in high-stakes matches was highlighted by their dominant performance against England at Twickenham earlier in the year.
Gavin Furlong, who played for the British and Irish Lions on a recent tour, has been cleared of any disciplinary breach regarding an incident involving Gavin Coombes during a Leinster match.
With Furlong and former Lion Andrew Porter available for selection, head coach Andy Farrell and scrum coach John Fogarty must formulate a strategy to strengthen Ireland's set-piece dominance.
World Cup preparations were reportedly advancing smoothly at the time these concerns about recent results emerged.
Persistent losses to New Zealand, South Africa and France have prompted questions regarding the squad's trajectory as next year's tournament approaches.
The pattern of poor outcomes against major rivals remains a primary area of focus for the coaching staff.
