It may not prove to be the case in the long run, but New Zealand feel a little vulnerable going into the 2019 Rugby World Cup.
Having failed to win this year's shortened version of the Rugby Championship, the All Blacks are no longer the top-ranked side prior to the tournament in Japan.
Admittedly, they have not suffered a World Cup defeat since 2007, when they were stunned by France in a quarter-final in Cardiff. Their pedigree, plus their strength in depth, means Steve Hansen's side deserve to be considered the favourites.
Still, there is a glimmer of hope for the rest of the rugby heavyweights. The question is: who is best placed to dethrone the champions?
1. SOUTH AFRICA
Could the Springboks be peaking at just the right time? They won the Rugby Championship for the fourth time this year and, after a shocking start against Japan, came as close as any nation to ending New Zealand's march towards a second straight World Cup in 2015. An early crack at the All Blacks in their Pool B opener will give them the chance to land a potentially telling blow. Also, the Boks ruled the world in 1995 and 2007. Now, 12 years on from their previous success, will the trend be repeated? They deserve to be viewed as the main contenders to the defending champions.
It cannot possibly go any worse than four years ago, right? Eddie Jones – who was in charge of the Japan team that upset the Boks in Brighton in 2015 – is at the helm and the schedule has aided their campaign, as they have Tonga and the United States in their opening two fixtures in Pool C, giving them a chance to iron out any issues before they round out the stage by facing Argentina and France. The talismanic Owen Farrell is the key – and not just because of his outstanding kicking off the tee.
Warren Gatland could finish his spell in charge by doing a Six Nations Grand Slam and World Cup double. The Kiwi reached the semi-finals in 2011 and then the quarters four years ago. The reason they are not rated higher, however, is the list of absentees. Flanker Taulupe Faletau and fly-half Gareth Anscombe are missing due to injuries, scrum-half Rhys Webb is unavailable due to selection rules and attack coach Rob Howley has returned home over an alleged betting breach.
Like several of his counterparts, Joe Schmidt's tenure comes to an end with the World Cup. His final Six Nations did not go quite to plan, but Ireland top the world rankings, defeated New Zealand less than a year ago (in a game where the mighty All Blacks failed to score a try) and have plenty of experience in their squad. Much will depend on the form and fitness of fly-half Johnny Sexton - can he help the team recapture the form they displayed in 2018? While Pool A looks to be plain sailing, they face the prospect of New Zealand or South Africa in the last eight.
The beaten finalists from four years ago will be relying on experience to go one better than 2015. Michael Cheika has often seemed on the brink as their head coach, but he raised hopes by beating New Zealand 47-26 in Perth in August. Still, they lost the rematch 36-0 on the road and are minus their leading strike weapon in Israel Folau, who is locked in a legal dispute with the Australia Rugby Union following his sacking for comments on social media. Without him, they will be more workmanlike than eye-catching in attack.
Scotland are in a pool that, apart from Ireland, looks softer than some of the alternative options. They will not take hosts Japan for granted in their final round-robin fixture and, if they do progress, will have to cause an upset against either New Zealand or South Africa in the next round. Gregor Townsend has plenty of World Cup experience from his playing days, but this is his first in charge of the national team - expect the Scots to be in some highly entertaining contests but the last four looks a long shot.
Los Pumas languish outside the top 10 in the rankings but have made the semi-finals at two of the last three World Cups. The reason they are listed so low here, though, is their group. Only two can progress and having been drawn alongside England and France, Argentina face a challenge to make the quarters. Mario Ledesma's squad is dominated by players from Jaguares, who reached the Super Rugby final for the first time this year, but will lean on the Stade Francais' Nicolas Sanchez to provide control.
There was a time when France were the team you wanted to avoid in the knockout stages (just ask New Zealand 12 years ago, while they only won the 2011 final 8-7 against Les Bleus). Yet this current bunch are not living up to previous versions, with a distinct lack of flair put down to a domestic game now dominated by big-name overseas recruits occupying key positions. Sure, France have turned it on for the big occasion in the past, but the 2019 squad should concentrate first on making it out of their pool.
AND THE REST...
Japan have improved since 2015. Italy? Not so much. The hosts can justifiably think a quarter-final slot is within reach, but the Azzurri look doomed in Pool B alongside the All Blacks and the Boks. Currently placed inside the world's top 10, Fiji will likely have to beat one of Australia or Wales just to make it out of their group. The other nations will hope for damage limitation against the big boys and aim to take points off each other in their remaining fixtures.
