final swim. When the USA is playing sports against the world, the US tends to tune in and watch. Very few people care about swimming and diving and very few people watch it. The fact that 32.7 million people in the US watched Phelps swim his final race isn't any indication that the format of the Olympic games is the best tournament format in the world. All it means is that the US is the third or fourth most populous country in the world, and people will watch a US athlete or US team representing our country compete.
