Preamble: Here we have a play Argentina ran from a scrum. A9 passes flat to A10. He has A14 come up right alongside him. A12 and A13 cross, with A13 angling in towards A10. A10 engages S23 (functioning as 10) and pays no attention to S9. A13 condenses in, pulling S10 (functioning as 12) in. A14 ghosts behind A13, receives a short ball from A10 and darts around A13 into space vacated by S10. S13 is too wide to cover the run by A14 and A12. Result: A14 advances a large distance into Bok territory.
Question: How should the Boks have defended? Who was at fault for the break?
