The Six Nations has been nothing but unpredictable so far.
With three rounds gone, some teams have surpassed pre-tournament expectations while others have failed to deliver on their potential.
And then there's been drama off the pitch, too.
Here, we assess every team’s performance so far.
Top of the table with three wins out of three, it could not be going any better.
Wayne Pivac’s side may have had a slice of luck along the way, seeing opponents reduced to 14 men in the opening two games as they beat Ireland and Scotland.
Then there was the controversy of the two tries which set them on their way against England in round three but it was a comfortable 40-24 victory in the end.
Wales are now the title favourites and are two wins away from a second Grand Slam in three years. If Scotland are awarded a walkover victory over France, Wales could even win the title just by beating Italy.
Strengths : If you want to know why Wales have improved so much from 2020 to 2021 then you need to look no further than the defence as a starting point.
A large number of points being shipped cost Byron Hayward his job in November but Wales’ defence has been key to their success in the tournament so far with the three top tacklers in the tournament, and six of the top 10.
Wales have also been clinical in taking their chances when they have come along, with Louis Rees-Zammit leading the way as the tournament’s top try scorer - crossing the whitewash three times.
Weaknesses: Although it is another area that has improved since the autumn, the lineout is still a concern for Wales and they struggled in particular against Ireland here.
And while the defensive stats are impressive, it also tells a story that Wales have not been able to dominate in terms of possession as they would like.
As Pivac warned, Wales have not played their best yet.
Star man: Louis Rees-Zammit
There are several contenders but nobody has quite had the impact of the young winger, who scored the decisive tries against Ireland and Scotland with some superb finishes and has emerged as the sport’s newest superstar.
Rising star: Callum Sheedy
The fly-half is yet to start a Six Nations game but is making an impact from the bench and scored a match-winning 13 points against England.
A fantastic start saw France thrash Italy and follow that up with a hard-fought win over Ireland in Dublin.
However, a Covid outbreak has threatened to derail their title bid and their match against Scotland was postponed with 11 players missing and the squad in self-isolation.
With threats from the French government that they could be withdrawn after it emerged that head coach Fabien Galthie had left the Covid bubble to watch his son play rugby, a tournament which started with huge promise could end in disgrace.
Strengths : Not many teams can live with France when they are in full flow with the ball in hand and their offload game flourishes.
They have been able to match that with a hard-nosed defensive edge since the arrival of Shaun Edwards as defence coach last year and looked like the best all-round team in the opening two rounds.
Weaknesses : We’ve all heard the old adage that you don’t know which France team are going to turn up and they have a knack of imploding.
Last year it was a red card to Mohamed Haouas at Murrayfield which proved fatal to their title hopes and, while they seem to have found a level of consistency on the pitch, this time it is events off it that threatens to cost them.
Since it emerged that Fabian Galthie left the Six Nations bubble and players went out for waffles in Rome, there have been calls for Scotland to be awarded a walkover victory.
Star man: Antoine Dupont
He made four try assists in the opening round win over Italy and won the crucial turnover against Ireland at the death. One of the best in the world.
Rising star: Dylan Cretin
The 23-year-old flanker scored the first try of the tournament in his first Six Nations start and showed plenty of promise as he made 39 metres.
The men in green sit third on seven points after two losing bonus points from narrow defeats and a thumping victory over Italy on Saturday.
Peter O’Mahony’s red card hurt their hopes in the opening day 21-16 defeat to Wales in Cardiff and they lost by just two points at home to France in round two.
Strengths: Ireland have had the better of possession in every game they have played so far. They also have the top performers in the competition when it comes to carries and metres made in James Lowe and CJ Stander respectively.
Andy Farrell’s side have a strong set piece which gives them a good base to play off and some exciting backs with the return of captain Johnny Sexton giving them a big boost in Rome.
Weaknesses: Turning possession into points. Ireland have been let down by a lack of clinical finishing, poor decision-making and accuracy when it matters most, as epitomised by the penalty kick which missed touch when they had a great chance to win in Cardiff.
It was a similar story against France as they lacked the ruthless edge to finish tries off.
Rugby is a game of fine margins and Ireland could easily be sitting in Wales’ position with three wins out of three if they had taken their chances.
Star man: Tadhg Beirne
The former Scarlets man is having an outstanding tournament, leading the way in turnovers so far.
Rising star: Hugo Keenan
The 24-year-old is second on the list of metres made, clocking up an impressive 316 so far, and he scored two well-taken tries in Rome on Saturday.
It has been an abject title defence with two defeats in the first three games to leave them lying fourth on six points.
England were poor in their opening day defeat to Scotland and improved slightly to beat Italy comfortably before losing to Wales.
Strengths: England have some dangerous players and when they move the ball through the hands quickly they are very threatening, as shown in glimpses against Wales, with quality finishers like Anthony Watson and Jonny May able to finish off.
Weaknesses: Indiscipline. The 41 penalties England have given away is the joint highest in the tournament along with Italy.
It cost them dearly against Scotland where they struggled to get any decent field position as a result and again in Cardiff when 14 penalties enabled Wales to surge clear.
Star man: Anthony Watson
He has three tries in three games and has looked dangerous when England have been able to get the ball in his hands.
Rising star: Jack Willis
Scored a try on his Six Nations debut against Italy only to cruelly have his tournament ended early by a horror knee injury almost immediately after. A bright future beckons if he can recover.
Sitting one place off the bottom with five points from two games, but it does not really tell the story of Scotland’s tournament.
They were superb against England and were unlucky to lose against Wales as Zander Fagerson’s red card proved costly.
Scotland have a game in hand on the teams above them following the postponement of their game against France.
Strengths: They have been strong up front and over-powered England at Twickenham.
Scotland are one of the most attractive teams to watch as well with Finn Russell pulling the strings.
Weaknesses: Like Ireland, they have not been clinical enough in the red zone. Even against England, Scotland should have won by more than the five-point margin as they dominated possession and territory.
And even though people will point to the red card against Wales, they also failed to take chances in big moments that allowed the momentum to swing.
Star man: Stuart Hogg
The skipper has led by example with some outstanding performances, seeing him awarded man of the match against England and scoring twice against Wales.
Rising star: Cameron Redpath
Enjoyed an outstanding debut against England and looked at home in international rugby, only for injury to rule him out against Wales.
It has been a familiar story for Italy so far with three defeats taking them to 30 in a row in the competition – a run which stretches back to 2015.
They shipped 50 points against France and 40-plus against England and Italy, losing by a combined 101 points so far.
Strengths : Italy do have exciting young players, particularly in the back line, with head coach Franco Smith hoping that by giving them experience now they will be more competitive in a few years. They have looked dangerous in attack at times.
Weaknesses: Their defence has been woeful. It is simply too easy to score against Italy.
They are also not as strong up front as Italy sides of the past.
Star man: Monty Ioane
Scored a fine try to give Italy the lead against England and has made 316 metres so far, the third best in the tournament.
Rising star: Stephen Varney
The Welsh-born 19-year-old represents the next generation for Italy having been trusted at scrum-half and had some bright moments against France and England.
