How England can turn the odds and beat South Africa.
Priority number one. France conceded three first-half tries after South Africa's kicking game had created backfield chaos.
On the first Gael Fickou, sightlines blocked by the hulking Eben Etzebeth, failed to claim Cobus Reinach's box-kick and Kurt Lee-Arendse feasted on the scraps.
On the second, Cameron Woki juggled a Manie Libbok crossfield bomb into the grateful arms of Damian de Allende.
On the third, Jesse Kriel poked a grubber into wide, open space for Cheslin Kolbe to scamper in.
Three tries, 19 points and just a three-point deficit after France had dominated other metrics by far wider margins.
"France in the first half, with the ball, were absolutely unbelievable," said former England international Paul Grayson on the BBC's Rugby Union Daily podcast.
"But South Africa had done nothing and got three tries, which I wouldn't say they were given by France but they would certainly go down as assists.
"England have to deal with it. Your backfield coverage and defusing anything that goes into the air has to be spectacular. That needs to be error-free, dominant and controlling the airwaves."
Marcus Smith, who has been a exciting, novel full-back option for England at the tournament, was unavailable to Borthwick, having failed a return-to-play test after their win over Fiji.
But Freddie Steward was always the best solution to stem the flow of points that dashed French hopes.
Eight inches taller than Smith and with a track record as a specialist, he will be key to nullifying South Africa's kick-to-compete ploy in attack.
Borthwick may also ponder whether the Boks are vulnerable to their own tactic. Arendse and Kolbe may have the edge on Jonny May and Elliot Daly for speed but, at 5ft 10in and 5ft 7in respectively, they are giving up height.
Could England isolate them in aerial contests on attack?
