Johnny Sexton knows only too well what it's like to play a leading role in losing a test to the All Blacks, a cruel learning experience which has only made him better and, perhaps as a result, he has enjoyed two victories against the world champions.
The second of course was in Wellington last weekend when he combined so brilliantly with his No12 Owen Farrell to contain and then expose the All Blacks in the Lions' 24-21 victory.
The first was last November in Chicago when he orchestrated Ireland's famous victory over the All Blacks which put a stop to their 18-test winning run. It was a thoroughly deserved win, too, one with daring and skill - a bit like the Lions' triumph at Westpac Stadium.
The failure was in Dublin in 2013, a night when Sexton should have enjoyed his first victory over the All Blacks, and who knows what might have transpired if he had. There he was in the eerie hush of a filled-to-capacity Aviva Stadium with Ireland ahead 22-17 and only six minutes on the clock, a relatively easy penalty to kick to take the test beyond the visitors.
Alas, for him he pushed it to the right and his shoulders seemed to slump on his way back to his own territory; the belief of the crowd and his teammates dissipating into the cold air as he ran.
