I think it has more to do with the ability to design then the ability to race. Would prefer to see a true OD but I doubt that is going to happen.
At the end of the day, at least looking at the pure performance numbers of these two boats, you are very close to OD performance.
What's killing Oracle is bad starts, strategic mistakes, and general sloppiness. The only win they have came when NZ were guilty of these same things.
NZ is just better, smarter, and more consistent than OR. It's not really about the boats at this point.
