Rick Bianco submitted this image taken with a Digital Rebel XT, at 1/200 sec, f/9, ISO 400. Rick stated that he had used post processing to blur the background. He used a 75-300mm lens and could have set the aperture differently to open it up to f/4.5 or f/5.6 to blur the background while keeping the main subject in focus. Opening up the aperture would also allow a faster shutter speed at a lower ISO. All good things, a cleaner image, less post processing and still freeze the action.
