We've got four teams and roughly 10 times that many intriguing storylines left in the men's basketball portion of the Rio Olympics.
It's elimination time now. A loss at this stage means bronze is the best possible outcome, and nobody wants to come this far for bronze. Spain and America square off in half of the Friday bracket, while Serbia and Australia will do battle in the other. The winners advance to the gold medal game.
The stakes are high, and Team USA's somewhat surprising vulnerability (don't get too caught up in that blowout win over an overmatched Argentina team in the quarterfinals) means the competition is a little more open than most would have expected.
