How can anyone stop the Springboks?

After the second round of the Nations Championship Alfie Reynolds, Stuart Barnes and Charlie Morgan look back on all of the action. They ask which nation might be able to compete with South Africa at the next World Cup and what style of rugby could cause them problems. That's after a weakened Springboks team beat Scotland despite an impressive display from Gregor Townsend's men. Plus, are the All Blacks under Dave Rennie once again playing to their strengths? Should Henry Pollock start for England away in Argentina? And, Peter O'Reilly looks ahead to Ireland's trip to Eden Park.
