Years of watching the Canes beat all the good teams away, and then lose at home to yer ma and a few of her mates make any victory a surprise (it’s more about getting to the final than beating the Lions as such).
Plus up until then I was convinced Wellington sport was cursed sometime in the 1980s - we’d always lose for ridiculous reasons (‘you have the best running backs in the entire rugby world? Good news! We’re playing the final in completely unexpected fog and your players won’t be able to see more than 5 metres’. ‘Beat everyone in the round robin? The most economic bowler in the country will break his hand fielding early in the final’…etc).
