I can't find it either. I always felt as a kid that players who made their name in the UK were soft on defence. You had your exceptions like Hanley but generally it's what let NZ and GB down.What an enigma of a player kvin Iro was. At his best the greatest on the planet, just unstoppable...most of the time he wasn't like that though.
I remember him scoring an end to end try at Brookvale, starting from his in goal. He never even thought of forcing it for a drop out, he picked it up and ran across the in goal.
He just kept running and fending off players, and scored under the posts at the other end. Breathtaking skill. I cannot find it on YouTube though.
