I know that I should never take the SMF bait but...have you considered that France, Australia, Lithuania, and Spain exist when you are ranking national teams? Or that over the past 40 years that the second Americas slots for the Olympics have been filled by only Brazil, who are always good and during that period featured one of the great scorers of all time, or the golden generation of Argentine basketball (an Argentina that is still ranked 4th in the world)?
Canada has underachieved recently to be sure but they aren't some sort of historical underachiever at all, they just weren't very good until around 5 years ago and still have quite a ways to go.
In other news, the Czechs are dominating Rick Pitino's Greece team early on in the first so I'm really enjoying a very upset Pitino so far.
Update: The Czechs are up 27 now after three quarters and are just murdering Greece on the glass with 11 offensive boards to just 9 defensive boards for Greece. Their three headed center situation has 40 points, 15 boards, and 10 assists so far. We may have to allow that Czechia is just, you know, good.
Pitino now just looks sad and defeated but is still at least cursing during timeouts.
