"Sports photographs exists to not just freeze the action, but to also capture the human form in motion and the emotion of a moment. They should show us the emotions of sacrifice, the drive, the gut wrenching disappointment, and the ultimate goal of victory.
I strive to ensure the photo will mean something to the subject and/or the spectator, but most of all it should capture a moment and have a reason to exist."..... me
