No doubt as the who will occupy the number six shirt this week but a number of toss-ups elsewhere. Ireland delivered the most complete display of the weekend so they dominate.
France and Ireland continue on course for a Grand Slam decider after comprehensive wins over Wales and Italy respectively while England overcame a parasite-ridden Murrayfield pitch and passionate Scotland resistance to keep their Championship hopes alive.
The tournament takes a fortnight's break before a hugely decisive weekend when Ireland travel to Twickenham with a Triple Crown the prize on offer, Wales will look to bounce back in Cardiff against Les Bleus and Scotland v Italy in Rome will surely decide the destination of the dreaded wooden spoon.
Peter O'Mahony shone brightest of all this weekend, Here are the 14 others to make the grade:
15. Rob Kearney (Ireland)
A consummate display of full-back play, ruled the airwaves and gave a timely reminder that, had he been able to report for duty fit last summer, Leigh Halfpenny might not have had it all his own way. Definitely more aggression to his game this season.
14. Hugo Bonneval (France)
Got on the end of the move of the weekend to dot down France's third try to cap an impressive display on his debut.
13. Luther Burrell (England)
Two caps, two tries. Took a great line to score from a flat pass by Danny Care, almost scored a second just before half-time and moved ball well all evening
12. Wesley Fofana (France)
Bringing the form he shows for Clermont week-in and week-out to the international stage. His dynamism and speed have made him the outstanding inside centre of the tournament thus far. His solo try showed what the 26-year-old is capable of
11. Jonny May (England)
Burst into the game after a largely quiet first half, with his pace and footwork bringing a new edge to the England attack during the second half.
10. Jonathan Sexton (Ireland)
A little ropey from hand early on, but his decision-making was crucial and his accuracy in turning the Welsh defenders went a long way to starving them of momentum. Goalkicking excellent and tactical kicking imperious.
9. Conor Murray (Ireland)
Once he was described as a young Mike Phillips, but on Saturday he made the cranky Welsh scrum-half look old. Growing with every game, he takes pressure off Sexton and leads by example. Turning into one of the best exponents of box-kicking in the world.
1. Joe Marler (England)
Made some massive hits in the close exchanges to set the tone and made a number of gainline-breaking carries. Will be a potent weapon at set-piece time when Ireland visit Twickenham.
2. Rory Best (Ireland)
One huge turnover in the Irish '22', plenty of big tackles and a faultless line-out throwing performance, the Ulster hooker is one of Ireland's most important players. Dylan Hartley unlucky to miss out on selection.
3. Dan Cole (England)
Eradicated the scrummaging problems from his Paris display with a strong display both in the set piece and at the breakdown.
4. Courteney Lawes (England)
Was one of England's leading carriers and his aggressive tackling was key to denying Scotland momentum up front. When he gets momentum in his tackling, he can be devastating.
5. Paul O'Connell (Ireland)
His massive hit on Dan Lydiate helped set the tone and, considering he is still sick, the totemic Munster second-row gave quite a display before being hauled ashore. He and Toner completely dominated the lineout.
6. Peter O'Mahony (Ireland)
Man of the match for what should be the second game running, his work on the ground is one of the major reasons Ireland have yet to concede a try in the Championship. Only his singing was a little bit off.
7. Chris Robshaw (England)
The captain set the tone for England's forwards in difficult conditions with his commitment and dominated the breakdown.
8. Jamie Heaslip (Ireland)
The vice-captain comfortably outplayed Toby Faletau and the absence of Sean O'Brien appears to have allowed him to re-invent himself again. Ireland's top tackler. Billy Vunipola was a very close second at number eight.
