And of course its apples and oranges.
In the badminton game... both teams were doing it! Both were trying to tank! And in any event, when you beat your opponent it's only to 15 points, and the game ends quickly.
Compare that to our professional basketball players, who have been rolling over their opponents. When they played Nigeria, they made 29 three-point shots. Why take three point shots when you're destroying your opponent?
Should they have stopped playing entirely and walked off after the third quarter, declaring the win? No, of course not. Keep playing, keep running plays, but why go for the daggers, the 3-point shots? Just to run up the score and rub it in the face of your opponents.
