What resilience and composure from Team GB to recover.

I really thought GB were dead and buried at 21-0 down. The Americans were all over Great Britain in the first half. But that try just before half-time gave them a pulse. That was the message at half time and then it was one way traffic, resolute defence at the end and a five point victory to take them to the semi-finals.
