City of lights...and an NBA team?
Is this guy nuts? First, some city in a Podunk cornfield and then Paris, France?
It seems clear to me that the NBA's business plan involves more eyeballs on screen and more jerseys off racks in places that aren't in North America—Europe and China especially. There was talk a few years back about hosting the All-Star Game in Paris, and there's also been talk of a European Division of the NBA. Some of this coming from the Angel of Stern himself.
(My plan would add a European Division and also solve the contraction issue that's floating around the NBA: Instead of contracting, move a few less-profitable, smaller-market teams to Europe.)
Even though the O2 in London is bigger than Palais Omnisports, Paris gets the nod in my mind because of the All-Star proposal and the fact that France is much more of a basketball-playing nation than Great Britain (and building a new arena probably wouldn't hurt). But if there is a whole division, London would likely get a team as well.
So my 10th and final pick is Paris, as a representative of possible NBA expansion into Europe. I know that, in comparison to the other cities on my list, this is the least likely, which is why it is last on my list.
Even if they don't try Europe, I think it's quite possible that the NBA will try to have a second non-American team. There's been talk that Vancouver's trying to get a group together (though I'd much rather see one in Seattle than Vancouver, especially if Vancouver Take II has anywhere near the quality that Vancouver Take I had in six seasons).
If the NBA wants to put a second team in Canada, my vote is for Montreal. Montreal is a bigger metro area than Vancouver; Bell Centre is a much bigger and better venue than Rogers Arena. The French have also proven to be quite interested in basketball, and Montreal is colder in the winter than Vancouver, lending itself more to indoor events. Frankly, I think that NBA and MLB Canadian expansion would've worked better if the MLB went to Vancouver and the NBA went to Montreal.
So there you have it...nine American cities, and the specter of international expansion.
