Not at all. Have you any idea the cost for fielding a team, teh design work, building two boats, and racing for three years to get to the Cup finals? There is a reason that only very, very rich individuals take part in these things...
NZ and the US have a long, LONG history in America's Cup lore actually.
Let's see, there was the whole Dennis Conner "they're cheating" with the glass boat in 1987, after which he beat them 4-1 when they had lost 1 race the entire challenger series (I believe Kiwi Magic was 33-1 or some other ridiculous win% through 3 round robins, losing only to Stars and Stripes by like 1 second).
Then the big boat challenge in 1988 where the US raced them in the catamaran. They could have litterally sailed circles around them and still won. One of the darkest days in AC history, IMO.
In 1992, the Kiwis were smoking Conner's team with NZL-20, until Conner raised yet another cheating claim against thier bowsprit, causing them to have to modify thier boat on the fly. They then got wiped.
And this year, guess who is Team Oracle CEO of sailing operations? None other than the Golden Boy himself, Russell Coutts, the man who finally brought the Cup to NZ in dominating fashion in 1995 at the helm of Black Magic. Talk about kicking them in the stones! About the only thing that would have hurt worse is if Sir Peter Blake rose from the dead to start his own US team...
