A referee blows his whistle as a couple of players fall on each other.

The good: Shows a struggle for the ball, an incident the referee has to intervene and stop the play. This is really good for the sports team. Let's say the UCLA player had an awesome game, a couple of goals and such; the article could focus on her, and they could use this picture.

The bad: My center focus point slipped and suddenly moved to the background. This is the only shot in focus; the others are focusing on the wrong thing. This can happen to anyone, so make sure you track the ball well.
