France v England
And play magically Wales, Ireland and England did in their bids to win the title on points difference, with Ireland triumphing but only after a crazy, ding-dong 55-35 battle at Twickenham between England and France.
This Saturday's concluding triple-header promises to be every bit as encapsulating. England have secured the Championship and seek a Grand Slam in Paris, however don't expect any nerves to inhibit them or the atmosphere at the Stade de France in the evening to be anything but electric despite Les Bleus' toils.
Before that, Scotland arrive in Dublin buzzing after back-to-back wins following nine tournament defeats on the trot but face hosts who rediscovered their mojo in racking up 50 points against Italy at the Aviva last Saturday.
While Wales will be out to wallop the poor Azzurri again in Cardiff at lunchtime and take out their frustrations at being beaten by England last week, yet Sergio Parisse and Martin Castrogiovanni will want to give Jacques Brunel some semblance of a fond farewell.
England have banished their recent World Cup and Six Nations ghosts at every turn so far, with a solid win at Murrayfield, second-half surges against Italy and Ireland and a first-hour tour de force against Wales, and they can turn the ever-present smile on Eddie Jones's public face into a full-on Cheshire Cat grin with a first Slam success since 2003.
They are deserved champions and performing much more fluently than France in the pack, half-backs and backs. Home head coach Guy Noves's decision to change only his Backrow from the listless 29-18 defeat in Edinburgh on Sunday is unlikely to alter this significantly.
But it is unlikely to be a procession so have small bets on England winning the game by 1 to 12 points and England giving up 3.5 points on the second-half handicap.
What bringing back the bruising Bernard le Roux is designed to do is limit the early damage that Billy Vunipola and Maro Itoje do on the charge for England, who are still giving away too many cheap penalties through Dan Cole and James Haskell in particular.
And France have sensational backs for broken, unfettered play in Virimi Vakatawa, Wesley Fofana and Gael Fickou.
However, key talkers in the Red Rose set-up captain Dylan Hartley, ex-skipper Chris Robshaw, Dan Cole and Owen Farrell will be telling the rest how they won 24-22 in Paris four years ago, while two years ago they so nearly weathered the storm of conceding two early tries in a 26-24 defeat.
Rather than suffering last-gasp disappointment, England should be staying on at the end for the spoils and they will not mind an end-to-end encounter on the way either with fizzing backs of their own in Anthony Watson, Jonathan Joseph, Jack Nowell and Mike Brown. Indeed, Jones has gone some way to anticipating such a battle by picking Danny Care at Scrum-Half and Mako Vunipola may well have started at Loosehead even if Joe Marler had not been waiting on disciplinary hearings this week.
For a tryscorer bet, take Manu Tuilagi at 7-1. Tuilagi will be raring to be unleashed off the England replacements bench and he stormed up the touchline four years ago to kickstart that surprise success. Scotland with an eight-point start is the bet in Dublin.
Ireland v Scotland
Ireland did romp to victory on Saturday with Donnacha Ryan, Josh van der Flier and CJ Stander hitting every ruck for 50 minutes like they were still in the hunt for the title but they were flattered by how easily Italy fell apart. Last year's 40-10 Edinburgh win and the last two big-margin Dublin successes look a long way away.
Wales v Italy
So George North has to be the go to man in this game for two tries and a hat-trick or more. North has scored in Wales' last three games against Scotland, France and England to show that he is definitely finally over his concussion issues. He also scored a hat-trick in last year's 61-20 win in Rome when Wales scored eight. Wales's changes won't affect their power and rhythm. Italy are without their midfield spark and defensive lynchpin Michele Campagnaro.
