Sir Russell has done for the sport what T20 did for cricket, making it enjoyable to the wider public.
A friend of mine recounted a story to me a few years ago - he was hosting an American company executive for a few days and had decided to take him to a one-day cricket international at Eden Park. It was a New Zealand vs Australia match, which was one of those very exciting games where it all came down to the final few balls being bowled before a result was known (I believe New Zealand won that particular match).
Afterwards, my friend asked his American colleague what he thought of the match, to which the American responded, "It was great, but do you guys have a short version of this game?"
Of course this was funny at the time, as the ODI was the short version of the game, but several years later the advent of T20 has compressed the entire cricket concept down to just a few short hours and, it would seem, gained huge worldwide appeal as a result.
As I sat on the edge of my seat yesterday morning watching Emirates Team New Zealand racing Oracle Team USA in the giant AC72 catamarans, I was struck by just how truly exciting this America's Cup has been as a spectator sport.
