On it's own, nothing. Even a gold medal won over the US will provide nothing but short term hype on it's own. Soccer had an event to themselves, perfect timing with their re-launch, and amazing organisation/promotion all built up from a couple of years out and ready to go. Basketball has none of that, and I doubt they will. A medal on it's own might gain a slight grassroots movement in interest, but will not translate to anything mass or any greater success for the NBL unless it is backed by a huge amount of work on the NBL/BA's part. I just don't think they're up for it. From what they say from time to time, I think they think it's the opposite. Get a medal, and everything else will naturaly fall into place. If they really think that, they're very, very, very wrong. They'll have 24hrs of hype until some swimmer breaks their 5th record of the event or something, then that will be it.
