Although there is a family sitting in the stands watching the game, I had to search for them to figure out how this fit the topic. They do not strike me as the main subject, though I can appreciate how you thought this fit the challenge theme.
I do see what you were going for here, and it's a nice capture of the action, but I don't feel it really fits family. Maybe if the focus was on a particular family in the stands, it could have fit better.
