Stuart Lancaster may have been hoping for 4 wins out of 4 in the Autumn internationals. The loss to the All Blacks England can take on the chin. Stuart Lancaster would have been targeting the match against South Africa as one to win.
Lancaster would have noticed the complete capitulation of the Springbok scrum in their Test against Argentina in Salta earlier in the year. He would see as an opportunity their subsequent loss of structure and discipline.
Target the scrum , keep the scoreboard ticking from the penalties gained from the pressure at scrum time. That way you create pressure on the scoreboard and force them to play catch up rugby. When a team plays catch up they take chances, mistakes inevitably happen that is when England can pounce. Turnover ball is the perfect time to launch an all out assault on the oppositions try line.
With the inexperienced Cobus Reinach at scrum half the England pack will put a premium on shunting the Springbok scrum backwards. Ball going backwards and being under pressure results in mistakes by the Springboks.
England are more likely to target Jannie du Plessis as he has been found out several times in the past.
A little word in the ear of Steve Walsh the referee about scrumming inwards beforehand can’t hurt.
