I give you credit for actually capturing the action of a sport, thank you. Faster shutter speed would obviously help to freeze the motion (though I know many cameras aren't capable). It looks like there was also a bit of camera shake, which doesn't help with the blur. Post-processing was a little overdone, perhaps on contrast, so the colors look a bit unnatural. And of course everyone on this site loves impossibly clean backgrounds, so if you could shoot this from an angle with less background clutter that would help.
Great action and interesting lighting. However, there are some compositional problems with this picture. The background is very busy and distracting. The guys feet are cut off and the football gets lost in the telephone pole.
nothing seems to be in focus, the ball is almost invisable, the way it lines up with the pole, and the crop looks odd at the bottem, with his feet cut off, a difarent location would have helped.
