Just watched it.
I was impressed by the fact we mostly beat them up front - lot of strong carries in close - however the scrum seemed to lose concentration at vital moments which hurt. Overall a good performance from the forwards against England, who you would expect could dominate this area.
An offside cancelling out Martens' try and the missed kicks would be hurting them.
I just don't know how we get dished up by the Boks, narrowly beat Scotland, and then play that well, only to lose.
